| 摘 要： | 采用AFORS-HET软件对CsGeI3空穴传输层(Hole Transport Material, HTM)平面异质结钙钛矿太阳电池进行了模拟,TiO2作为电子传输层,CH3NH3PbI3作为光吸收层,C作为背电极,分别讨论了钙钛矿光吸收层厚度、缺陷浓度,光吸收层/HTM界面态密度和HTM对太阳电池性能参数的影响.模拟优化得到CsGeI3 HTM的PSCs最佳性能参数为:Voc=1.199 V,Jsc=22.2 mA·cm-2,FF=86.22;,PCE=22.95;,效率虽略低于spiro作为HTM的器件,但考虑生产工艺和制备成本,CsGeI3作为HTM的PSCs将具有更好的应用前景.

| Abstract: | Planar heterojunction perovskite solar cells (PSCs) with CsGeI3 as hole transport materials (HTM) are simulated by AFORS-HET software.In the PSCs, TiO2 is used as electron transport layer, CH3NH3PbI3 is the light absorption layer, and C is the back electrode.The influences of light absorption layer, CH3NH3PbI3/CsGeI3 interface and HTM on the solar cell performances are discussed.The simulation results show that the optimal parameters of the PSCs are: Voc=1.199 V, Jsc=22.2 mA·cm-2, FF=86.22%, and PCE=22.95%.These performances of the CsGeI3 HTM PSCs are close to those of the spiro HTM PSCs.While if the production process and the preparation cost are considered, the PSCs with CsGeI3 as HTM will have better application prospect. |
