초록

Perovskite solar cells have exhibited a remarkable increase in efficiency from an initial 3.8% to 26.1%, marking a significant advancement. However, challenges persist in the commercialization of perovskite solar cells due to their low stability with respect to humidity, light exposure, and temperature. Moreover, the instability of the organic charge transport layer underscores the need for exploring inorganic alternatives. In the manufacturing process of the perovskite solar cells' oxide charge transport layer, ultraviolet-ozone (UVO) treatment is commonly applied to enhance the wettability of the perovskite solution. The UVO treatment on metal oxides has proven effective in suppressing surface oxygen vacancies and removing surface organic contaminants. This study focused on the characterization of nickel oxide as the hole transport material in perovskite solar cells, specifically investigating the impact of UVO treatment on film properties. Through this analysis, changes induced by the UVO treatment were observed, and consequent alterations in the device characteristics were identified.
