A Flinders University researcher has been developing a cheaper and faster way of making large-scale plastic solar cells using a lamination technique, paving the way for a lucrative new clean energy industry.
The novel method, developed by PhD candidate Anirudh Sharma (pictured), is a promising alternative to the expensive fabrication techniques currently used in the renewable energy sector, and would make the commercialisation of plastic solar cell technology more viable.
While plastic solar cells have been researched for the past 15 years, Mr Sharma said the current fabrication process, which involves vacuum conditions, was still relatively expensive and time-intensive for large-scale production compared to his lamination technique.
“In the conventional method of fabricating plastic solar cells you have to deposit various materials sequentially on top of each other in a sandwich structure but over time the materials intermix, leading to device degradation,” Mr Sharma, based in the School of Chemical and Physical Sciences, said.
“However my technique involves deposition of materials on two different electrically conductive surfaces, followed by lamination. It gives better control over the material intermixing and thus can give more stable and better performing devices,” he said.
“The entire lamination process is roll-to-roll compatible, which means that the lamination technique could be integrated with printing machines similar to newspaper printers.
Therefore the materials can be deposited by printing and devices can be fabricated by lamination at the same time, making the entire process scalable at relatively much lower costs.
“This is a much cheaper way of fabricating solar cells because you can make a large number of devices in a very short time, and this method of self-encapsulation can potentially help improve the life-span of the device as well.”
Mr Sharma said plastic solar cells were a cheaper and more sustainable form of renewable energy compared with silicon-based devices.
“For the past 50 years, the traditional solar panels which you see on rooftops have been made from silicon but these cells are very expensive to produce because silicon requires excessive amounts of energy to purify.
“Plastic solar cells, on the other hand, are really light and flexible so they can be used to coat a whole range of different surfaces – they are portable enough to put them on day to day carry bags and even camping tents – and plastic itself is cheap as chips.
“Building developers are already looking at integrating plastic solar cells with the latest building designs by using plastic solar cell-coated window panes for new buildings so this technology will definitely replace silicon in the very near future.
“And my research shows real promise for a faster, more cost-effective way of making plastic cells.”
Mr Sharma was one of eight finalists in Flinders University’s 2012 Three Minute Thesis, a competition encouraging PhD students to explain their research in simple terms.

Please keep me informed of your progress with the ( Flinder )cell panels and future distribution opportunities. Best regards John De Nicolo.
Awesome work, great going. All the best for your success.
Well done Anirudh. You have made DehraDun feel proud of your great achievement. Great going! we are waiting for your more such feats.
Great work. If you have some time ,I wanted to talk to you regarding this in more detail. On what email address can i reach you?
Kudos dude!Wish you all the best for successful commercialisation nd also your PhD !
Wonderful news! I’ve been looking forwrd for this product for a long time. This can be intergrated into vehicle roof tops, front back and side panels to generate electricity during day (& night – from street lamps, other vehicles)) for hybrid type technology. Major power distributors will not be happy with cheaper & local generation reducing their profit margins. Wish you all the best in your PhD and the future of commercialising this very important product. Talk to Hybrid vehicle manufacturers to incorporate this into their vehicles body parts.
Terrific breakthrough. Would you be interested in having the new product field tested for water runoff, weather testing, etc. We’ve got a field experiment almost set up to determine moiture runoof rates and potential chemical weathering.
This is brilliant! One of the major hurdles currently faced by the solar industry is of course high costs. It’s very exciting to see advancements like these in solar technology. I wonder if Flinders Uni and Anirudh Sharma have made more progress on this project in the last 2 years?
Great research! Solar energy will be one of the most important energy source for the next generation. Plastic solar cells can make this type of energy available to everyone from family houses to big companies. I wonder at what stage the research is now. I cannot find much information about plastic solar cells anywhere.
