摘要
通过分别使用四元合金Cu_2ZnSnS_4和Cu_2ZnSnSe_4量子点代替钙钛矿太阳能电池中昂贵的有机空穴传输材料spiro-OMeTAD~([1]),探究了带隙对钙钛矿电池性能的影响,深入研究了引起钙钛矿电池开路电压损失的物理原因,最终证明宽带隙的无机空穴传输材料更适用于高效率的钙钛矿电池。
Quaternary Cu_2ZnSnS_4 and Cu_2ZnSnSe_4 alloy QDs were respectively used as hole-transporting material(HTM) instead of the expensive organic HTM(spiro-OMeTAD) in perovskite solar cells. The influences of band gap on cell performances were discussed. The physical origin of open-circuit voltage losses was further discoveried. The inorganic HTM with wide band gap is certified a more favorable materials for efficient perovskite solar cells.
