Organic solar cells are becoming an important technology for next-generation energy applications since they can be made into flexible and lightweight devices. However, attaining thermal stability remains a significant challenge for its actual deployment. Heat-induced morphological alterations within the photoactive layer typically led to considerable performance reductions. It's interesting to note that this effect may be reversed in some circumstances. Our investigations on P3HT:PCBM solar cells show that devices subjected to high-temperature exposure (up to 250°C) demonstrated substantial performance recovery upon cooling. Thermally driven and reversible morphological change in the active layer was demonstrated by photoluminescence analysis.
