Surface treatment by decyl‐phosphonic acid (DPA) reduces the recombination and increases the open circuit voltage and the fill factor of the inorganic–organic Sb 2 S 3 hetrojunction solar cell. It is revealed that the DPA attaches to both surfaces, the uncovered TiO 2 surface and the Sb 2 S 3 surface. This cell produces a power conversion efficiency of 3.9% under 1 sun intensity.
