In organic solar cells (OSCs), the necessity of UV activation that comes with the use of ZnO‐ and TiO x ‐based electron extraction layers (EELs) can be avoided by using tin oxide (SnO x ), which can be prepared at temperatures as low as 80 °C. In contrast to devices based on TiO x and ZnO, OSCs comprising SnO x as the EEL show well‐behaved solar cell characteristics with a high fill factor (FF) and high efficiency, even without the UV spectral range of the AM1.5 solar spectrum.
