已经开发了实验室实验，研究使用光原电池将光转化为电能的基本过程。光电流电池的基本组成部分是光电极，由烧结在导电玻璃上的纳米晶TiO 2（TiO 2）薄层组成;低成本反电极（电动剃须刀的镀铂剃须刀箔）;以及电解质溶液中的不同牺牲供体。这些简单的电池适用于课堂调查，检查光电流电池的工作原理和不同参数对其效率的影响。通过这些实验，教师可以将现代研究和技术的主题引入课程。
Laboratory experiments examining the fundamental processes in the conversion of light into electrical energy using photogalvanic cells have been developed. The basic components of the photogalvanic cells are photoelectrodes, consisting of a thin layer of nanocrystalline TiO2 (anatase) sintered on conductive glass; low-cost counter electrodes (platinized razor foils from electric razors); and different sacrificial donors in the electrolyte solution. These simple cells are suitable for classroom investigations examining the operating principles of photogalvanic cells and the influence of different parameters on their efficiency. With these experiments instructors can introduce topics of modern research and technology into the curriculum.
