Problems solved by technology

TiO 2 As the photoanode semiconductor material with the most application potential at present, although it has the advantages of photostability, high catalytic activity, and non-toxicity, it can only use the ultraviolet part of sunlight because of its wide band gap (3.2eV). The utilization of visible light is low, which restricts the photoelectric efficiency, which is a common problem encountered by dye-sensitized solar cells
