Abstract
Effects of co-addition of CuBr2 and NaCl to CH3NH3PbI3(Cl) perovskite solar cells were investigated on the photovoltaic properties and microstructures. Short-circuit current densities and conversion efficiencies were improved by the simultaneous addition of CuBr2 and NaCl. In addition, the efficiencies of the devices were maintained even after 10 weeks. The perovskite structure changed from a tetragonal to a cubic system by the addition of Na, which resulted in the improvement in the stabilization of the perovskite crystal.
