Abstract

The enhanced photoelectric performance of quantum dot sensitized solar cells via hydrogenated TiO₂ is proposed. The best energy conversion efficiency is 1.5 times higher than cells without hydrogen treatment. We demonstrated that introducing oxygen vacancies by hydrogenation is an effective and feasible method for enhanced photoelectric performance.
