在能量转换效率和长期稳定性方面表现出最高的性能，尽管由于电荷传输的固有限制，效率保持在13%以下。光电极的结构是决定光电化学系统功能性质的关键。特别是，光阳极由具有高比表面积（通常是体相对应物的一千倍）的中孔宽带隙氧化物半导体膜组成。
exhibit the highest performance interms of energy conversion efficiency and long term stability,despite the fact that the efficiency remains below 13%because of the intrinsic limitation in charge transport. Thestructure of the photoelectrodes is crucial in determining thefunctional properties of the photoelectrochemical system. Inparticular, the photoanode consists of a mesoporous wide-band-gap oxide semiconductor film with a high specificsurface (typically a thousand times larger than the bulkcounterpart).
