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%

We demonstrated that two Lewis bases – urea and thiourea – acted as efficient additives for CH(3)NH(3)(MA)PbI(3−x)Cl(x) 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 ex...

Sumario:We demonstrated that two Lewis bases – urea and thiourea – acted as efficient additives for CH(3)NH(3)(MA)PbI(3−x)Cl(x) 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 °C).
