A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells perform well in different light conditions including partial shade making them well matched to consumer electronic devices such as e-book readers, cameras and some mobile phones.
