ABSTRACT:
A cell for the direct conversion of radiant energy to electrical energy for arrying the process is characterized in that it comprises two layer-like zones each comprising a transparent material and at least one photochromic compound, electrical conduction means between said two zones, and two electrodes. The two layer-like zones may be constituted by different portions of a same layer. The photochromic compounds used are preferably spiro-2H-pyranes and the electrodes are metals having a standard oxidation potential higher than--2.5V or their oxides or photoactive semi-conductors.
