Ottova et al. looked at two-compartment semiconductor-septum electrochemical photovoltaic cells with cadmium selenide and cadmium selenide telluride for water photolysis [126], They used cells consisting of two chambers separated by a CdSe or CdSe/CdTe bipolar electrode. The bipolar electrodes were prepared by painting a CdSe slurry on a metal substrate or by ultrasound-aided electrodeposition from CdSe solution in ZnCl2. The photoresponse (voltage and current output) and hydrogen yield from photo-induced electrolysis of H20 in the dark chamber of the cell were evaluated as a function of CdSe preparation method. The ultrasound-aided deposition technique gave excellent coatings of CdSe. 

Indeed, based on experience gained in pigmented BLM research in artificial photosynthesis, a novel type of photoelectric cell, termed a semiconductor septum electrochemical photovoltaic (SC-SEP) cell, has been developed. In a SC-SEP cell, a semiconductor septum (e.g., CdSe) is used in place of a pigmented BLM to separate two aqueous solutions. When light shines on the semiconductor membrane, photoinduced redox reactions are observed (82-84). Operation under short-circuit conditions allows the cell to be used for photolysis of water using solar energy (85).
