Abstract
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 UO.sub.2.sup.2+. The liquid system comprises a second constituent which is a cation and more particularly Ce.sup.3+. The second constituent can also be an anion and in particular NO.sub.3.sup.- or SCN.sup.-. 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.
