Fiscal 1975 Sunshine Project research report. Research on hydrogen production technology mainly by photo- semiconductor; 1975 nendo hikari handotai wo shutai to suru suiso seizo gijutsu no kenkyu seika hokokusho

Abstract

In fiscal 1975, to study the possibility of photochemical decomposition as new hydrogen production technique based on the research result in the preceding fiscal year, study was made on some materials useful as electrode for photocells among various semiconducting materials with large solar photo-electromotive force. Study was made on the kind and combination of electrode materials, and electrolyte composition for photocells through measurement of photocell characteristics by various combinations of semiconductor electrodes. As for the impact of light sources, study was made on the photosensitization phenomenon by xenon light, solar light and xenon lights with various spectral profiles through specific filters, and the relation between a light intensity and hydrogen efficiency. As useful semiconductor photocell electrode systems, combinations of n-type GaP or n- type GaAs and p-type GaP or p-type GaAs were most efficient. As preventive technique of semiconductor electrodes from dissolution, coating technique of various materials showed insufficient results. (NEDO)
