Abstract

Perovskite solar cells (PSCs) are currently attracting attention as a promising source of photovoltaic power generation for their rapid increase in efficiency within a short research period. However, the 2-step deposition method, which has been considered as a proper film fabrication route in commercialization point of view of PSC, requires a complicated control of environment to achieve high efficiency because each step of the process are affected by humidity in different manner. It is clearly a large hurdle for this technic to be transferred to industrialization. In this study, we developed a simple surface treatment by which high quality perovskite films can be fabricated through 2-step deposition method in a relatively wide humidity range without complicated humidity control at each step.
