Limited heat dissipation at perovskite interfaces causes local overheating and accelerates degradation in perovskite photovoltaics. Now a solution-processable alkynyl-porphyrin conjugated polymer is inserted between the perovskite and hole-transport layers to enhance interfacial heat dissipation while maintaining efficient charge transport. This thermal and electronic management boosts device efficiency and operational stability.
