Photoelectrochemical cell assembly having electrolyte contacts between semiconductor surfaces
First Claim
1. An assembly comprising at least two separated semiconductor electrodes, each of said semiconductor electrodes having a positive and negative surface with a photoactive junction therebetween, one of said surfaces of each electrode being exposed for contact with an electrolyte and the other being isolated from said electrolyte, and said electrolyte for electrically connecting in series said exposed surfaces of opposite polarity of said at least two semiconductor electrodes, said electrolyte comprising at least one redox couple capable of a reversible redox reaction with one exposed surface of each of said semiconductor electrodes whereby the composition of said electrolyte remains substantially unchanged as charge is passed between said electrodes.
