New Horizons for Perovskite Solar Cells Employing DNA-CTMA as the Hole-Transporting Material

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 20.85mAcm(-2), open circuit voltage of 1.04V, and fill factor of 73.15%, and improved lifetime. DNA-based devices maintained above 85% of the initial efficiency after 50days in air.
