Perovskite has high absorption, low exciton binding energy, and a long diffusion length. Thus perovskite solar cell device recently show n brilliant efficiency. But perovskite solar cell has a natural defect site that deteriorates PV factors. Therefore, defect site restoration improve the solar cell performance. Introducing polymer is one of the effective methods. Polymer passivate perovskite grain boundary, and block the oxygen, humidity. Previous research mention blocking the oxygen, humidity. In this study, we introduce optical tunning. |
