| 摘 要： | 该文研究加热和水处理共同作用对PbI2薄膜形貌的调控和对钙钛矿太阳电池性能的影响。使用的钙钛矿体系为（FAPbI3）1-x（MAPbBr3）x,并在两步法工艺基础上对PbI2薄膜进行不同时间加热和短时间水处理可将PbI2薄膜制备成多孔结构。将双重处理后的PbI2薄膜制备成钙钛矿薄膜后,可发现钙钛矿薄膜质量明显提升,表现在：钙钛矿的晶粒尺寸明显增大、结晶性增强、吸光能力提升、载流子传输更快。且此种方式能有效调控钙钛矿薄膜中的PbI2残留量。在器件效率方面,只对PbI2薄膜进行加热处理制备的电池的开路电压、短路电流、填充因子和效率分别为1.05 V、23.12 mA/cm2、73.81%和17.92%,而在最优双重处理工艺下制备的电池的这4个相应的参数分别为1.09 V、24.75 mA/cm2、77.85%和21.10%。

| Abstract: | In this paper, the combined effect of heating and water processing on the control of PbI2 film morphology and its influence on the performance of perovskite solar cells are studied. The perovskite system used is （FAPbI3）1-x（MAPbBr3）x, and the PbI2 film can be prepared into a porous structure by heating the PbI2 film for different times and short-time water processing on the basis of a two-step method. The quality of the perovskite film prepared by the dual-processing is significantly improved, which is manifested in the obvious increase in the grain size of the perovskite, enhanced crystallinity, increased light absorption and faster carrier transport. And this method can effectively control the residual amount of PbI2 in the perovskite film. The open-circuit voltage, short-circuit current, fill factor and efficiency of the cell prepared by heated PbI2 film are 1.05 V, 23.12 mA/cm2, 73.81% and 17.92%, respectively. These four corresponding parameters of the cell prepared under the optimal dual processing are 1.09 V, 24.75 mA/cm2, 77.85% and 21.10%, respectively. |
