39 V and boosts the efficiency to a certified value of 20. Our findings provide an avenue for defect passivation to further improve. The advantages and drawbacks of each type of cell are also presented Enhancing the efficiency and stability of perovskite solar cells Chieh-Ting Lin Department of Materials, Imperial College London December 2019. Given all exciting properties it also shows some very challenging characteristics such as hysteresis in light IV measurement, environmental instability, voltage evolution, self-degradation in dark and photon-induced degradation solar panel costly. When a solar cell is exposed to light, a portion of the photon with the energy larger than the bandgap is absorbed by the semiconductor.
