Light-based production of drug-discovery molecules
(PHYSorg.com Chemistry)

Photoelectrochemical (PEC) cells are widely studied for the conversion of solar energy into chemical fuels. They use photocathodes and photoanodes to `split` water into hydrogen and oxygen respectively. PEC cells can work under mild conditions with light, which makes them also suitable for other catalyzing reactions that turn organic molecules into high added-value chemicals, like those used to develop drugs.
