Abstract

Solar energy has been the most emphasized issue in recent years, as it is sustainable and causes zero emissions. Solar cells are of interest because they convert sunlight into electricity through photovoltaic effects. Over the last ten years, the efficiency of perovskite solar cells has achieved 25% due to the development of synthesis techniques and electrode materials etc. The electron transport layer, a hole transport layer their thickness and structure of surface etc. act an important role in improving the performance of perovskite solar cells. We have investigated the effect of the acid-assisted route and the acetylacetone-assisted (AA) route on TiO2 films and thus the effect of the efficiency of perovskite solar cells. Perovskite (CH3NH3PbI3) solar cells based on different c-TiO2 have been fabricated by the spin coating route, and the overall experimental section is made in the nitrogen medium at room temperature. Cracked c-TiO2 film obtained via the acid-assisted route. The planar heterojunction structure of ITO/AA-TiO2/CH3NH3PbI3/P3HT/Ag resulted 0.03% of power conversion efficiency (PCE). However, the perovskite solar cells with a mesoporous heterojunction structure of ITO/ AA-TiO2/m- TiO2 /CH3NH3PbI3/P3HT/Ag resulted 0.1% of PCE.

钙钛矿太阳能电池的制备与性能:乙酰丙酮对TiO2致密层的影响

太阳能是近年来最受重视的问题，因为它是可持续的，零排放。太阳能电池之所以引起人们的兴趣，是因为它们通过光电效应将阳光转化为电能。近十年来，由于合成技术和电极材料等方面的发展，钙钛矿太阳能电池的效率已达到25%。电子输运层、空穴输运层的厚度和表面结构等对提高钙钛矿太阳能电池的性能起着重要的作用。我们研究了酸辅助路线和乙酰丙酮辅助(AA)路线对TiO2薄膜的影响，从而对钙钛矿太阳能电池效率的影响。采用自旋镀膜的方法制备了基于不同c-TiO2的钙钛矿(CH3NH3PbI3)太阳能电池，并在室温下在氮气介质中进行了整体实验。酸助法制备c-TiO2薄膜。ITO/AA-TiO2/CH3NH3PbI3/P3HT/Ag的平面异质结结构可获得0.03%的功率转换效率(PCE)。然而，具有ITO/ AA-TiO2/m- TiO2/ CH3NH3PbI3/P3HT/Ag介孔异质结结构的钙钛矿太阳能电池的PCE为0.1%。
