The Reliability And Prolonged Time In Single-Junction Gaas Solar Cell With Perovskite Quantum Dots

In this experiment, we demonstrate high reliability of CsPbBr3 Perovskite Quantum Dots (PeQDs) which illuminates 530 nm wavelength photons by exciting source on GaAs single-junction solar cell (Above 3000 h) and explore the Luminescent Down Shifting (LDS) effect of the GaAs solar cell with PeQDs with and without thermal process. The best one result shows that J(sc) from 23.85 mA/cm(2) to 22.99 mA/cm(2) (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.
