摘　　要：以α相三氧化二铁替换了传统二氧化钛电子传输层,同时以LAD掺杂PTAA替换传统Spiro-OmeTAD空穴传输层,制备具有新颖结构的钙钛矿太阳能电池.通过对其进行老化测试,重点探究其对于紫外、水汽破坏的抵抗能力.虽然这种新结构电池的能量转换效率(12.39%)略低于传统的钙钛矿电池结构(14.19%).但是在紫外稳定性与水汽稳定性方面有显著的提升,从而提升了电池的使用寿命,具有重要的现实意义.Perovskite solar cells with novel structure were prepared by replacing the traditional titanium dioxide electronic transport layer and Spiro-OmeTAD hole transport layer with alpha-phase ferric oxide(α-Fe2 O3)and LAD-doped PTAA,respectively.The stability of the novel device under the condition of UV irradiation and humidity was tested through the artificial aging experiment.Although the power conversion efficiency of the novel device(12.39%)is slightly less than that of the traditional one(14.19%),the ultraviolet stability and water vapor stability are improved significantly.Therefore,the lifetime of the novel perovskite solar cells can be significantly improved,which is crucial for the real application.
