摘要：

We demonstrated that two Lewis bases - urea and thiourea - acted as efficient additives for CH3NH3(MA)PbI3-xClx and MAPbI(3) perovskite solar cells (PSCs) and observed a significant increase in PCE for the MAPbI(3) devices in the presence of 1% urea with a remarkable PCE of 18.8% using an extremely low annealing temperature (85 degrees C).
