Abstract

We established a system for simultaneous measurements of photoelectrochemical (PEC) reaction and photoabsorption in a semiconductor photoelectrode. This system uses a photoacoustic technique and photoelectrodes with a film-thickness gradient that was prepared by electrophoretic deposition of tungsten(VI) oxide particles while pulling up a substrate. The system enabled high-throughput determination of optimum film thickness, and the results showed that irradiation direction has a significant influence on PEC performance for a photoelectrode with a thick film. Furthermore, the mechanism of enhancement of PEC performance by postnecking treatment was discussed.

半导体光电极厚度优化的光吸收和光电化学性能的同时测量

我们建立了一种同时测量半导体光电极中光电化学反应和光吸收的系统。该系统采用光声技术和薄膜厚度梯度的光电极，该薄膜厚度梯度是在拉起衬底的同时电泳沉积钨(VI)氧化物颗粒制备的。该系统实现了最佳膜厚的高通量测定，结果表明，辐照方向对具有厚膜的光电极的PEC性能有显著影响。进一步探讨了后颈处理提高PEC性能的机理。
