Abstract
This paper is referring to photo-electrochemical systems for water cleavage into hydrogen and oxygen, wherewith it is realized the pure ecologic cycle of solar energy conversion. It was obtained the patents for two installation realized in scheme of tandem photo-electrochemical cells. Its performances consist in increasing yield of solar energy conversion in chemical energy of the water decomposition components which can amount from 8-10% to 30% values.
