钙钛矿太阳能电池空穴传输材料——NiOx的制备及应用

随着经济和科技的发展，世界各国加深了对能源的依赖，能源危机愈演愈烈，作为可再生能源中的太阳能备受瞩目，太阳能从发展至今已经研发出多种太阳能电池，其中钙钛矿太阳能电池因其成本低廉、可柔性、高效等特点备受瞩目。钙钛矿太阳能电池自从被发现以来，短短数年间，光电转换效率从最初的不足 5%短短几年内就超过 22%，只用了不到十年的时间，赶超了其他太阳能电池发展四十年乃至更多的成果。对于钙钛矿太阳能电池，它的空穴传输材料对其性能影响巨大，目前常用的多为有机材料，成本高昂，且影响钙钛矿太阳能电池的稳定性，本文力图制备一种无机空穴传输材料——NiOx，成本低廉，性能优异。钙钛矿太阳能电池目前的制备工艺主要是在手套箱中旋涂为主，手套箱中旋涂很难将钙钛矿太阳能电池产业化，本文深入研究了空气中热辅助刮涂技术，该技术可作为基础，转化为卷对卷等印刷工艺，因此更有利于钙钛矿太阳能电池的商业化。在此基础上，将制备好的性能优异的无机空穴传输材料NiOx 应用于空气中热辅助刮涂中，进一步改善电池的性能，降低成本，从而为钙钛矿太阳能电池商业化提供坚实基础。

With economic and technological development, the world has greatly increased its dependence on energy and the energy crisis has greatly increased. As the solar energy in renewable energy has drawn much attention, a large number of solar cells have been developed since the development of solar energy. Among them, perovskite solar cell attracted much attention due to its low cost, flexible, high efficiency and other characteristics. The hole transporting material of perovskite solar cell has great influence on its performance. At present, most commonly used organic materials are high cost and affect the stability of perovskite solar cells. In this paper, an inorganic hole transporting material – NiOx will be prepared,and it cost low and has excellent performance. Preparation technology of perovskite solar cell current mainly is spin-coating in the glove box, spin-coating in the glove box is difficult to industrialization for perovskite solar cells, this paper will study of thermal-assisted blade-coating in air which can transform into a roll-to-roll printing process.On this basis, NiOx, an inorganic hole transporting material with excellent properties, which was prepared will be applied in thermal-assisted blade-coating in air to further improve the performance of the cell and reduce the cost so as to provide a solid foundation for the commercialization of the perovskite solar cell.
