Figure 4. Stability characteristics of inverted OSCs employing different CILs. (A) Normalized PCE retention of devices with PDINN, PDINN/BCP, and PDINN/Cu-BCP during air storage at RT; (B) normalized PCE retention under thermal-humidity aging at 65 °C/65% RH. (C) normalized PCE retention under continuous 1 sun illumination at 25 °C and 25% RH.
