摘　　要：主要研究了FTO玻璃清洗工艺对无空穴传输层的碳电极钙钛矿太阳电池的光电性能影响,对比分析了常规清洗和引入三氯乙烯清洗的不同效果。实验结果表明:三氯乙烯的清洗将有助于制备更平整的Ti O2致密层,且后期制作的钙钛矿层覆盖率更高。相比未采用三氯乙烯清洗的样品,采用三氯乙烯清洗后制备的钙钛矿太阳电池短路电流密度有明显提高,且电池的工艺重复性明显提升。但缺少空穴传输层会极大影响钙钛矿太阳电池的转换效率,若能在廉价空穴传输层材料的制备工艺中获得突破,结合三氯乙烯的清洗,将有助于提升钙钛矿太阳电池的市场竞争力。The influences of FTO glass cleaning technology on performances of the perovskite solar cells with carbon electrode and without hole-transport-layer were studied,and the effects of routine cleaning and the introduction of trichloroethylene cleaning were analyzed.The results indicate that trichloroethylene cleaning will bring more smooth TiO2 dense layer and higher coverage of the perovskite layer.Compared to the solar cells with routine cleaning technique,the Jsc of perovskite solar cells with trichloroethylene cleaning were obviously improved,and also the processes repeatability of solar cells were obviously improved.While the PCE of perovskite solar cells would be greatly affected for the lacking of hole-transport-layer.If there are some technology breakthroughs in cheap hole-transport-layer material,combining with trichloroethylene cleaning,the market competition of perovskite solar cells will be greatly enhanced.
