The effects of guanidinium (C(NH[sub.2] )[sub.3] , GA) and cesium (Cs) co-additions on methylammonium lead iodide (CH[sub.3] NH[sub.3] PbI[sub.3] , MAPbI[sub.3] ) perovskite solar cells were investigated. The first-principles calculations on the density of the states and band structures showed a red...
