title = "Low-temperature, simple and efficient preparation of perovskite solar cells using Lewis bases urea and thiourea as additives: Stimulating large grain growth and providing a PCE up to 18.8%",
abstract = "We demonstrated that two Lewis bases-urea and thiourea-acted as efficient additives for CH3NH3(MA)PbI3-xClx and MAPbI3 perovskite solar cells (PSCs) and observed a significant increase in PCE for the MAPbI3 devices in the presence of 1% urea with a remarkable PCE of 18.8% using an extremely low annealing temperature (85 °C).",
