| 520 | _ | _ | |a The commercialization of perovskite solar cells (PSCs) depends on breakthroughs in stability, yet the complex degradation mechanisms complicate the study of their long-term performance. This work investigates the role of non-radiative recombination in PSC stability by establishing a quantitative link between defect-related parameters and device performance. We found that defect-induced minor losses in open-circuit voltage (VOC) are accompanied by significant reductions in charge extraction efficiency (short-circuit current and fill factor). Through non-destructive, contactless photoluminescence characterization, we decoupled non-radiative recombination effects in various perovskite stacks before and after accelerated ageing. The quasi-Fermi level splitting (QFLS) losses in devices during the ageing process primarily originate from the perovskite bulk rather than the interfaces, with most of these losses occurring within the first 50 hours of ageing. We find that optimizing perovskite composition and improving crystal quality to suppress defect formation during ageing can extend photo-thermal stability by more than a factor of 50. |
