| Outline of Final Research Achievements |
Perovskite solar cells have drastically progressed with respect to the photocurrent quantum efficiencies of more than 20%. Moreover, the perovskite layers have been advantageously prepared via low-temperature solution processes. Toward all solution-processed solar cells, solution-processed n- and p-type inorganic semiconductor thin-films controlled by nanometer thickness become a crucial key technology. In this study, mechanism on the low-temperature (150°C) crystal growth/interfacial connection of ZnO (n-type semiconductor) nanocrystals using a low-temperature flux has been elucidated. Crack and void-less nano-films of CuI and CuSCN (p-type semiconductor) have been successfully fabricated via a low-temperature (150°C) solution process. In this process, alcohol solvents are utilized to prepare the precursor solutions of CuI and CuSCN.
