Dong Seok Ham Korea Research Institute of Chemical Technology, Daejeon, --, South Korea

Perovskite solar cells (PSCs) have emerged as a promising candidate for flexible solar energy applications, boasting an impressive power conversion efficiency (PCE) of over 26.0%. However, a significant hurdle in their commercialization journey is the adaptation of perovskite materials to the roll-to-roll (R2R) coating process. This poster presentation aims to address this challenge by introducing innovative approaches and solutions. In this study, we present an anti-solvent method specifically designed to be compatible with R2R processing. This method aims to facilitate the seamless integration of perovskite materials into the R2R coating process, thereby enhancing the scalability and efficiency of PSC production. Through an experimental system, we elucidate the critical factors necessary for achieving uniform perovskite layers. Also, this poster includes detailed results into absorbance characteristics, surface morphology, and PCE measurements, guiding optimizing process parameters to maximize solar cell efficiency. Furthermore, we adapted the triple cation perovskite with the R2R process and it showed more superior PCE than MAPbI3 PSCs. We hope that our findings hold promise for significantly advancing the commercial viability of PSCs and accelerating their integration into large-scale.
