The Reliability and Prolonged time in Single-Junction GaAs Solar Cell with Perovskite Quantum Dots

In this experiment, we demonstrate high reliability of CsPbBr

(3.60% enhancement) and the efficiency from 17.41% to 15.57% (10.56% enhancement). The un-baked sample shows higher stability on EQE enhancement factor, slightly decreasing from 130% to 128%. Furtherly, the prolonged lifetime test for PeQDs exhibits considerable possibility in the future.
