The solar-to-electrical conversion efficiency of the photoelectrochemical cell p-InP/ VC13-VC12-HC1/C reaches 18.8%, when the surface of the p-InP photocathode is modified with Ag and doped witt Sn and the back contact is made with Cu.

• 本文报道了在p-InP/VCl_3-VCl_2-HCl/C光电池中改进p-InP光阴极的研究结果。 p-InP光阴极；经表面掺Sn、Ag修饰及形成Cu背面接触后；在阳光下的光电转换效率达18.；8%25。
