Since the invention of dye-sensitized solar cells (DSSCs), they have attracted increasing attention due to the advantages of low-cost fabrication and simple production processes compared with conventional silicon and thin-film solar cells. Generally, a DSSC consists of three components: a dye-sensitized photoanode, a redox electrolyte, and a counter electrode.
Our research group focuses on developing quasi-solid DSSCs with good stability and high performance. Flexible DSSCs are also studied. Moreover, we have succeeded in synthesizing nickel-doped TiO2 to improve the visible light activity of pure TiO2. Nickel-doped TiO2 has been used in the fabrication of the photoanode for DSSCs and has shown higher conversion efficiency.
