Abstract
The present invention provides a wet or dry bio-sensitized photoelectric conversion device (photodetector or photovoltaic) comprising: a stabilized biologically-derived sensitizer, such as a stablilized photosystem I (PS-I), deposited on nanowires, semiconductor material, electrodes and a support. The nanowires provide a greater surface area of the light absorption layer for better energy conversion efficiency and are chosen such as to complement the absorption spectrum of the sensitizer and protect the sensitizer from photobleaching.
