Toray Unveils More Efficient Solar Cell

Solar technology is the next big thing, but unfortunately for mankind and the rest of the world, the main bugbear of this green tech would be its extremely low level of conversion efficiency. Toray Industries Inc. breathes new hope into the industry by developing a new polymer donor material – the main material for organic thin-film solar cells, in a super thin form that has a conversion efficiency of 5.5%. This figure deposes the 5.15% record that was announced in academic conferences to date, and Toray hopes to further improve this material’s performance to hit a conversion efficiency of 7% by 2015. Good luck boys, you’ll need it.
