We investigate solution‐processed low‐temperature lead‐halide perovskite solar cells employing deoxyribose nucleic acid (DNA)–hexadecyl trimethyl ammonium chloride (CTMA) as the hole‐transport layer and (6,6)‐phenyl C 61 ‐butyric acid methyl ester (PCBM) as electron‐acceptor layer in an inverted p–i–n device configuration. The perovskite solar cells utilizing a bio‐based charge‐transport layer demonstrate power conversion efficiency values of 15.86 %, with short‐circuit current density of 20.85 mA cm −2 , open circuit voltage of 1.04 V, and fill factor of 73.15 %, and improved lifetime. DNA‐based devices maintained above 85 % of the initial efficiency after 50 days in air.
