摘要: The colors of solar cells are very important when adopting them for future indoor and outdoor light energy harvesting devices with smart designs. Here we report the formation of vividly colorful hybrid organometal trihalide perovskite solar cells by a low-cost and scalable doctor-blade coating method. The perovskite films have a combination of a hundred micrometer size large domain structure and a concentric ring photonics structure in each domain which generates the vivid color. The convection during precursor solution drying in …
