Abstract:
A regenerative photovoltaic photoelectrochemical device comprising two or more photoelectrochemical cells laminated between two substrates (1,12), with opposing electrical conductors (2,11) supported upon the internal surfaces of said substrates, wherein at least one conductor and its adjacent substrate is substantially transparent to visible light, and wherein said conductors on each substrate are each divided into electrically isolated regions, with each said cell being formed between parts of two regions of said opposing conductors and with each said cell comprising:a photoanode (3); a cathode (11); and an electrolyte medium (5) located between said photoanode and said cathode, and adjacent photoelectrochemical cells are electrically interconnected in series by an electrically interconnecting material comprising conductive particles (6), where said electrically conductive particles comprise particles of dimensions approximating the distance between said opposing conductors.
