N2 - In this study, we achieve the direct conversion of metallic Cu-In films to compound semiconductor CuInSe 2 films, at quite low temperature around 300 °C using less hazardous metalorganic selenium source in supercritical fluid (SCF). We investigated the effects of temperature and fluid (ethanol) density, and found that supercritical ethanol plays a crucial role in this low-temperature selenization reaction. Such SCF-assisted direct conversion reactions can facilitate large-scale, low-temperature, and rapid synthesis of CuInSe 2 films, which can potentially lead to the low-cost production of solar cells.
