Doo Kyung Moon and colleagues have developed flexible organic solar modules using a nonfullerene system through an evaporation-free all-solution process. This innovative approach allows for the creation of materials with balanced crystallinity, multifunctional hole transport layers, and a printing method suitable for large-area modules without evaporation. These flexible organic solar modules achieve a high efficiency of 5.25% and are promising candidates for industrial applications, such as building-integrated photovoltaics.-Scientific Journal cover by scapiens
