We demonstrated that two Lewis bases - urea and thiourea - acted as efficient additives for CHNH(MA)PbI Cl and MAPbI perovskite solar cells (PSCs) and observed a significant increase in PCE for the MAPbI devices in the presence of 1% urea with a remarkable PCE of 18.8% using an extremely low annealing temperature (85 °C).
我们证明,两种路易斯碱——尿素和硫脲——可作为CHNH(MA)PbI₃Cl和MAPbI₃钙钛矿太阳能电池(PSC)的有效添加剂,并观察到在1%尿素存在的情况下,MAPbI₃器件的功率转换效率(PCE)显著提高,在极低的退火温度(85°C)下,PCE高达18.8%。
