To boost the charge transport and collection processes in inverted organic solar device, gallium (Ga) was added to conventional TiO₂ film to form the Ga-TiO₂ film. Compared to the pristine film, the Ga-TiO₂ film showed better energy level alignment, which is in good agreement with the heightened ope...
