Here, a high-quality perovskite film with thermal and electrical conductivity dual enhancement are successfully constructed by using the self-synthesized conductive and thermally conductive self-healing supramolecular ionic polymer/hydroxylated boron nitride quantum dots (SMIP/h-BNQDs) additives to fabricate high-performance carbon-based PSCs without hole transport layer (HTL). Theoretical and experimental results indicate that the introduction of highly thermally conductive SMIP/h-BNQDs additives not only delays the crystallization process and passivates defects of perovskite film through the strong interactions of coordination and hydrogen bonds formed between them and perovskite components for improved film quality, but also accelerates heat transfer and dissipation within the perovskite film, thereby reducing the device operating temperature. The electrical conductivity of the perovskite film is also enhanced due to the incorporation of conductive SMIP/h-BNQDs, which facilitates charge transport. Moreover, the introduction of the self-healing SMIP/h-BNQDs additives significantly releases the residual tensile strain and suppresses the phase separation of the wind-bandgap perovskite film, endowing it with self-repair capability under mild thermal treatment. Consequently, the carbon-based HTL-free wide-bandgap PSCs fabricated in ambient air achieve a remarkable power conversion efficiency of 17.49 % and excellent operational stability under continuous illumination.
