摘要:
钛矿太阳能电池（PSC）通常由电子传输层（ETL）、钙钛矿光吸收层和空穴传输层组成，而电子传输层/钙钛矿层和钙钛矿层/空穴传输层的界面对钙钛矿薄膜的性质及太阳能电池的性能有较大影响。通过简单的旋涂法，在SnO-2电子传输层上旋涂一层NaCl层，来修饰SnO-2电子传输层与MAPbI-3钙钛矿光吸收层之间的界面。结果表明：NaCl修饰层不仅能提供部分Na+和Cl-溶解在钙钛矿前驱体中，辅助钙钛矿结晶，增大钙钛矿晶粒尺寸，而且NaCl能同时MAPbI-3钙钛矿层和SnO2电子传输层作用形成Pb—Cl和Sn—Cl键，使界面的化学结合增强，降低界面缺陷态，增强载流子的寿命和传输效率。此外，NaCl修饰层显著降低了电子传输层的功函数，使制得的器件开路电压高达1141 V，太阳能电池最终获得了高达19-49%的光电转换效率。
