Carbon electrodes have gained significant attention as a cost‐effective, sustainable, stable, and scalable replacement for metal in perovskite solar cells (PSCs). However, traditional carbon‐electrode‐based PSCs (C‐PSCs) lack hole‐selective layer (HSL) due to their incompatibility with the most effective organic HSLs employed PSC literature. In turn, absence of an HSL has been identified one main factors hindering performance C‐PSCs. Consequently, numerous studies recognized pivotal significance region between absorber carbon electrode C‐PSCs, proposing various interfacial engineering strategies improve these cells.
