Therefore, the quality of the perovskite film is determined by factors influencing crystal formation during the heat treatment process.<br /><br /></span></p> <p style="text-align: justify;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Professor Yongseok Jun and his research team have reported the effect of thermal equilibrium of water and atmospheric temperature on the formation of perovskite polycrystalline thin films during the heat treatment process. The research team found that the shape, crystallinity and orientation of the perovskite polycrystalline thin films differ depending on the difference in atmospheric thermal equilibrium, which directly affects the photoelectric conversion efficiency of the perovskite solar cell. In addition, it is suggested that a highly efficient perovskite solar cell with excellent reproducibility can be produced by controlling the atmospheric thermal equilibrium.<br /><br /></span></p> <p style="text-align: justify;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Professor Jun said that "this research will help to improve the process reproducibility of the perovskite solar cell by discovering and defining the process variables that have not been revealed in the process of producing the perovskite solar cell."<br /></span></p> <p style="text-align: justify; margin: 0cm 0cm 8pt;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">The research involved a doctoral student, Yohan Ko and a student at Master's degree, Chanyong Lee as a co-author. This research was supported by the Korea Research Foundation’s support for researchers in the field, development of technology for countering climate change, and industrial core technology development projects of the Ministry of Industry and Commerce.<br /><br /></span><img alt="" src="ArticleFile.do?id=11748486" width="627" height="821" /></p>
