Surface tailoring and functionalization of an annealed TiO2 compact layer by H2SO4 acid was performed to improve the dye-sensitized solar cell (DSSC) performance. Compared to untreated counterpart, the acid-treated compact layer possesses a rougher surface and more hydroxyl groups, which result in i...
