引言近年来,以半导体-电解质界面的Schottky势垒为基础的光电化学电池的研究,日益引起了人们的重视,因为它们可以直接将太阳能转变为电能和化学能。虽然目前已研究过的光电化学体系的能量转换效率尚低(仅达1％),但与已得到实际应用的固态P-N结半导体太阳能电池(转换效率已达12％)相比却有许多优越之处。如在固一固接界中易产 Introduction In recent years, research on photoelectrochemical cells based on the Schottky barrier at the semiconductor-electrolyte interface has drawn increasing attention as they can directly convert solar energy into electrical energy and chemical energy. Although the energy conversion efficiency of the photoelectrochemical system that has been studied so far is still low (only 1%), there are many advantages over solid PN junction semiconductor solar cells that have been actually used (conversion efficiency has reached 12%) Department. As in the solid one solid connection easy to produce
