摘要:
由于MAPbI 3钙钛矿薄膜缺陷较多，非辐射复合严重，导致钙钛矿太阳能电池性能较差。通过向前驱体溶液中加入3,4,5-三羟基苯甲酸（GA）作为添加剂来调控结晶过程，研究GA对钙钛矿薄膜质量和太阳能电池性能的影响。结果表明：GA中的羧基分散到钙钛矿前驱体溶液中，羧基中的氧原子与CH-3NH-3+形成强氢键，减缓了钙钛矿的结晶速度，增大了晶粒尺寸，减少了晶界，从而提高了载流子的迁移率，抑制了非辐射复合损失；当GA与PbI-2的摩尔比为1-0%时，钙钛矿太阳能电池的性能最佳，电池的短路电流为22-48 mA/cm-2，开路电压为1-09 V，得到了16-84%的光电转换效率，且经过800 h后，电池效率仍能保持在初始效率的87-0%以上。添加了GA后的钙钛矿薄膜具有更高效的光电性能，有望广泛应用于叠层太阳能电池领域。
