摘　　要：采用水热法合成CuGaO2微粒,研究了旋涂CuGaO2溶液前驱体浓度对薄膜质量和电池光电转换效率的影响。结果表明,当CuGaO2溶液的浓度为15mg/ml时,电池的光电转换效率有较明显的提高,达到了1.66%。以CuGaO2无机空穴传输材料替代传统昂贵的有机小分子材料,为进一步降低钙钛矿太阳能电池成本提供了一条切实可行的途径。CuGaO2 nanoparticles have been prepared successfully by a simple hydrothermal method and CuGaO2 films have been fabricated as hole transport layers in perovskite solar cells (PSCs).We investigated the processing parameter on the film-forming property and photoelectric conversion efficiency (PCE) of the solar cells.The results suggested that the PCE of the cells have been obvious improved (1.66%) by the spraying technology with the solution concentration of 15mg/ml.This work presents a new approach for expanding the possibilities for developing low-cost PSCs that do not require expensive small organic molecule materials.
