PHOTOELECTROCHEMICAL WATER SPLITTING FOR HYDROGEN PRODUCTION USING COMBINATION OF CIGS2 SOLAR CELL AND RuO_2 PHOTOCATALYST

摘要

This paper presents the development of photoelectrochemical (PEC) setup using multiple bandgap combination of CuIn_(1-x)Ga_xS_2 (CIGS2) thin-film photovoltaic (PV) cell and ruthenium oxide (RuO_2) photocatalyst. FSEC PV Materials Lab has developed a PEC setup consisting of two illuminated CIGS2 cells, a ruthenium oxide (RuO_2) anode deposited on titanium sheet for oxygen evolution and a platinum foil cathode for hydrogen evolution. With this combination, a PEC efficiency of 4.29% has been achieved.
