摘要
作为染料敏化太阳能电池的关键构成部分,对电极一直是研究的重点,尤其是硒化物对电极。本文采用恒电位沉积-溶剂热-硒化过程制备出钴镍基硒化物薄膜,并直接作为染料敏化太阳能电池的对电极。物相、形貌以及表面元素价态等分析表明,在氟掺杂氧化锡(FTO)玻璃上可直接获得NiCoSe_(4)薄膜,该薄膜是一种由纳米颗粒构成的片状多孔结构。电化学测试结果表明,NiCoSe_(4)薄膜在基于I-/I-3氧化还原电对的电解液中具有良好的电催化活性,由其构成的电池器件也展现出了良好的光伏性能,且光电转换效率达到了7.84%,高于铂基电池器件效率的6.95%。
Counter electrode is considered as a key component of dye-sensitized solar cells.Counter electrode,especially selenide counter electrode,has always been the focus of research.Nickel cobalt selenide film was prepared through the potentiostatic deposition-solvothermal-selenization process,and directly applied to dye-sensitized solar cells.Through the analysis of phase,morphology,and surface element valence state,NiCoSe_(4) film has been successfully synthesized on fluorine doped tin oxide(FTO)glass.NiCoSe_(4) film displays the sheet-like porous structure composed of nanoparticles.The results from electrochemical measurement demonstrate that NiCoSe_(4) film shows high electrocatalytic activity in electrolyte based on I-/I-3 redox pair.Dye-sensitized solar cell with NiCoSe_(4) film exhibits high photovoltaic performance.The corresponding photoelectric conversion efficiency is up to 7.84%,which is higher than that of platinum-based solar cells(6.95%).
