摘　　要：目前钙钛矿太阳能电池的认证效率已达25.2%,被认为是下一代最有希望的薄膜太阳能电池候选者。但通过溶液加工方法制备的钙钛矿薄膜不可控的形貌与较差的结晶性是制约器件稳定性提升和大面积生产的主要原因。为了有效解决这一难题,研究者们通常在电荷传输层与钙钛矿层之间进行界面修饰。本文从界面修饰的角度出发,总结了不同界面修饰策略在钙钛矿太阳能电池中的应用,并展望了界面修饰在低成本和大面积钙钛矿太阳能电池的应用前景。Recently,the certified efficiency of perovskite solar cells(PSCs)has reached 25.2%,which are considered to be the most promising candidate for next-generation thin-film solar cells.However,uncontrollable film morphology and poor crystallinity of perovskite prepared by the solution process restrict the improvement of stability and large-area production of PSCs.To solve this problem,researchers have carried out the interfacial modification between perovskite layer and charge transport layer.Herein,we summarize applications of strategies for interfacial modification in perovskite solar cells from the perspective of methods,materials,and characterization.Meanwhile,the promising prospects of interfacial modification in low-cost and large-area PSCs are provided.
