Abstract The inherently low thermal conductivity of conventional hole-transport layers (HTLs) in inverted perovskite solar cells (PSCs) introduces a substantial discrepancy in interlayer heat-transfer dynamics, leading to detrimental heat accumulation and nonradiative recombination. Herein, we develop a spinel-type semiconductor of CuBi2O4, and integrate it into a composite HTL architecture to regulate heat conduction for the first time.
