8bitfuture:

New flexible solar cells are thinner than spider silk.
Austrian scientists have developed flexible, stretchable solar cells on thin plastic foil substrates, able to generate a record 10 watts per gram. The cells have a 4.2% power conversion efficiency, which puts it ahead of this flexible solar system I covered earlier this week. Typical solar panels have around 12-17% efficiency.
The above image shows the cells being wrapped around a human hair only 70 microns wide. The cells are based on a commercially available substrate of PET film, with the total device measuring 1.9 microns thick - around a quarter of the thickness of traditional solar cells.
