Double‐Layer Passivation by Common Fullerene Materials for Ultraviolet Stability of Organic Solar Cells and Modules

Solar RRL, Volume 10, Issue 14, 29 July 2026.
UV‐induced degradation of OPV modules is substantially suppressed by PCBM/C60 bilayer passivation. The optimal PCBM/C60 (3 mg/mL) module retains 92% of its initial PCE after 1008 h of UV aging. Excess C60 concentration (5 mg/mL) reduces passivation effectiveness, highlighting the importance of interface optimization.
