PHOTOGALVANIC CELL USEFUL IN THE CONVERSION OF SOLAR ENERGY TO ELECTRICAL ENERGY

摘要

The photogalvanic cell is particularly intended for converting solar energy into electrical energy. The photogalvanic cell comprises two electrodes in a liquid system comprising a photosensitive constituent, which is formed by the uranyl ion UO22+. The liquid system comprises a second constituent which is a cation and more particularly Ce3+. The second constituent can also be an anion and in particular NO3- or SCN-. One of the electrodes is of polished platinum and the other of a chemically inert conductive substance, particularly graphite. The photogalvanic cell can also be coupled to a photovoltaic cell.
