my name is Ross on the and I'm from BTU energy
and in Denmark ominous also group headed by Professor Christian Creps a group about 35 people and we do most of our research within the community based on Motorola manufacturing but also we do a lot of work within the Stability and taxation and chemistry and I'm going to talk to you about some of the OPS dealings with been doing and did you at them 1st of all
everybody has a clear idea of solar cells and the reason why the scientists thinks is really interesting idea is and the amount of energy and that's available to and I think this picture represents this very well you see it all out and here the the the daily energy use as for the whole world and you see that the sun by 5 the largest capacity we have so
why do we want to work with the organic solar cells well if we go back to the originality behind the event also it's the prospect of having a very very very low cost that has been in the research the low-cost comes from the possibilities of solution processing which allows for manufacturing methods using roles role processing and which opens up the possibility to do flexible solar cells on the large areas using low temperature and on which again as gives a very low embodied in genes the funds also and because often the Mitchell selection of polymers as this becomes very very very big the possibilities are almost endless some of the issues with the source also and today still the lifetime of the salsa and also the efficiency
so just step very briefly Hollister and organic solar cell work it's an and multi-layer structure will be have several different layers ranging from few up to for 500 mm and the middle we have the actually is sober and this is surrounded by charge selectively which will allow either positive or negative charge too the and 2 Finally we have the electrodes 1 of which needs to be transparent in order for the light to and passed through the substrate and the actual Majuro self in New York and also often composed of 2 materials donor Jill and sedimentary material take to a very typically used Mogil's here flooring and P-3 to polymer what will happen when we shine light upon and the organics also is that as the Fulton will be a full of piety Paul Madonna plants you will create an exit on which is charge hole and electron and and this the exit sign will migrate to the interface between the donor and the except a material and will have charged operation after which there and different charges will track be transported to the respective 4 it is a
typical organics also prepared if we go to the left well size wise with deeply the talking the way below 1 square centimeter sufferers often used Internet site as the transparent electrodes and Spain growing
it is the typical way off and preparing thin films which means that you have an amount of liquid containing whatever substance 1 important opera substrate but it also means a lot of waste as The Exorcist ,comma discarded prices a really high performances can be achieve using these methods we're talking about 10 % that has been reported by most of the factors that I just mentioned are not scalable which is why we I'm more
interested in how to make it large-scale in meaning we need to look upon the whole process as a new thing size wise we're talking about square centimeters to square meters we're talking length of kilometres off oil and the general
emphasis that we have here did you and how prepare the solar cells is we need to try to to make a process that could be used as a product and and try and solve some of the stability issues that are related to you and you can it's also for
the organic solar cells to be competitive with other technologies added to processing these requirements mean that we don't waste any material we need to With the processes of use discuss material such as in Germany the indentation outside the as US transparent electrode is not an option we also need to think about the energy that you put into the solar cells so keeping the temperatures down making sure that you have and embodied energy in the final product that is much less than conventional facilities With respect to lifetime of such a technology we would be talking about years in order to consider this as a success so far and efficiency that Uganda's or sell on a larger scale is not as high as the small-scale devices which were 2 to 4 % and this of course means that if you want to use the technology for energy production on a larger scale and beyond the call gadgets then you need relatively large areas in order to achieved this you of course all the needs
of rolled through a machine a very briefly walking through the machine we start down that 80 people we have an on wider and the fall of leaves the role here and starts going into the machinery then it comes out to be wearing headscarves and lying the floor so we have the full placed exactly the same in exactly the same position during the whole process and we have the possibility to clean away Corona treat them and then we have various sprinting encoding stations we haven't yet flexible render I have never slept station although voters grandparents and aunts another oven before we reach the rewind away and the role of the final printers folded up
a fabrication lines we have all the methods man the encoding some engine we have the flick Supreme thing was which is you could say generally a continuous stabbing methods where Inc is picked up and buy a fountain roller transfer to an analog which is then again and transferred to the printing plates to cylinder which transfers it's onto the moving and you achieve the desired pattern in Rogers screen printing the ink is put inside a screen when you have a sweetener that squeezes the ink through and in In the screen onto the Web and finally we have slowed the coding work the English is passed through a slot occurring head and going through small slots inside the head and down to and this is God's will that you see the picture gives you the possibility to make stripes the 2 1st reflects bringing in water scraping up to to to the and mention that whereas the South occurring is one-dimensional you can only cold along the way How can this
be used to make an larger-scale installations and this is where the Infiniti projects we call it came into play place it
started out with I'm trying to make a new electrons and what called the flexed Road with his such chief as which basically consist of 1st the Flex apprentice Silver then we will screen printed please transparent .period and finally sink excitedly and allowing for an atrocity because
of the printed and character of the flexed wrote meaning you have still fingers covering some of the the area also the he that not completely transparent and the transparency of flexed showed is somewhat reduced with respect to I Geo but at the same time it has a really good conductivity and we found it I really good choice to substitute the ITO
OK stepped to the Infiniti marginal as In order to reduce the no amount of courage In module on a large area our strategy was to have instead high-voltage facility connected modules with many different men many In a separate solar cells working this allows for the look and allows for avoiding high ground was promised meaning that everything can be printed according to and the external wiring in the resulting there was also a lot you can have a thin outlined and you end up with something that had to terminals and no manual connections in the process
and so to go through the module it started out with the flex approved its celebrated agreed To told about form on top of the list sprinted averages screen-printed high conducted Peter then a layer of Singh excited in order to achieve electron selectivity many actually Peter appears as a whole selectivity and finally everything if finished off by Reuters screen printing on silverback to its throat and which also connects to their the different cells and you
can hear a small video of how the different promising and goes on
this small video shows the the different steps off the infinity module fabrication and 1st we start out with flecks of printing on the front electrode to sell followed by where strengthening of where the Indus squeezed through the screen and onto the cancel agreed this is followed by seemed excited about the coating where can see clearly the
ministers of the distinct size this is coated onto the Peter it's followed by the actively also processed with but subtitling this is changes again and finally we have 1st and Peter pieces in Sebago Lake Road which is the whole selective element of this there was also on this as follows 5 this is followed by silver screen printing for the back electrodes which also make this year the connections after printing and such printed print links could be ultra 700 meters of finalists also we typically took out a 100 meter stretches among the demand side and meaning we have around 21 thousand student connected saw cells and which gives you around 10 thousand volts efficiency wise the win I achieved with such stretches around 2 % which is relatively typical efficiency for a peace Grace to and Margalo which has been sold for process and it has thus been possible to transfer the results from the small technology to it really really large-scale where 100 % technicals yield is necessary in order and for them big module to function the bill is wiser it showed really high stability he steered the Kurdistan here that even after 3 three-stop thousand hours and this in the initial drop in the beginning but after that it's really really stable and the
resulting solar park here showing 6 stretches of solar cells product together the equipment that was used to mount it and and he is a
small video showing the actual mounting powerfully organic solar cell and them onto wooden scaffold 100 meters long time two-and-a-half meters he had a custom-built why can't builds and you and see how easily it's and simultaneously rolled out and attached to the wooden scaffold man the whole process of instead installing 100 meters takes around 1 minute from 1 end to the other after which the the foil is attached to the scaffold as you can see you scaffold can hold 6 and stretches of 6 modules of solar cells and
any connect and cereals 6 serious with each of the margins being 21 thousand cells we haven't actually area of around just below 90 square meters and the output of 1 . 3 kilowatts an energy bill times of around 180 days was achieved and lifetime wires the system is still running and it's almost 2 years ago so all in all that we consider this a great success also for small set up so we have adequate connections but this was for Small said as the system can take an as such high-voltage ' s with working with him we also wanted
to do some of installation with this set up on the Infiniti decides she can cut it out and lengths said you deem necessary so he tried to go both by air and water as well the solid
shooting water watch efficiency wise you see the somewhat more limited and because the angle toward the sun is not as good you see on the scaffold and also In the year
of the hats relatively good results I would not
recommend those that you start sending out 10 thousand or here in this case a thousand what mulches of India has if they detach that somebody could predicted 1 thing about this project is that it is quite dangerous and you need indication in order to work a system like this we also
had all share of failure modes and we had the was 1 we had a lightning strike on scaffolds Majesty resulted in serious burns office also and it's very difficult to put out a fire when you have 10 thousand volts and
you also have to the electrical failure for the most season and pictures will you the picture 8 you see how should be with last November lows and on any concedes will pinpoint holes where you can see that he is generated and so I cannot emphasize enough that care should be taking
a with such a set up it is possible that to repair the and we showed several different ways of doing it and smaller scratches could be the Fed simply by and covering the scratch with additional barrier fallen polyurethane glue the possibility of cutting out the defect area and rewiring itself and another 1 and if it's a larger segment you can simply cut out and replaced the segment as with anyone and this shows that how versatile the technology activities to
summon up we have shown that opening can be produced very fast the meeting was rumored that and and this can be done in a fully energy prices of the boys back steps we have prepared an electrode perplexed wrote which is high said efficiencies comparable to you in the final devices and it's possible To make a scalable high-power systems using pity all going the official said is I'm not very high on the
technology has short energy payback time and although the high-voltage has proven to be challenging if the source of is damaged he can be repaired and with this thank you
