"content": "Unencapsulated Pc-applied perovskite solar cells subjected to continuous heating at 85 °C in an N₂-filled glove box retain a power conversion efficiency drop of less than 5% after more than 1000 h, demonstrating thermal stability comparable to or exceeding that of metal-phthalocyanine-based devices. The result indicates that Pc itself is thermally stable and effectively suppresses out-diffusion and thermally induced volatilization of perovskite constituents, while also maintaining the doping components Li-TFSI and tBP at elevated temperature.",
