Dye-sensitized solar cells (DSSCs) have attracted much attention due to their simple structure, low-cost manufacturing process, promising energy conversion efficiency, and low environmental impact. In despite of their high energy conversion efficiency in DSSCs based on liquid electrolytes and N3 dye, but the potential problems caused by liquid electrolytes such as the leakage and volatilization of solvents, desorption and photo-degradation of attached dyes and corrosion of the Pt counter electrode. On the other hand, organic dyes have been also utilized as photosensitizers in DSSCs and recently, the solar cell performance of DSSCs based on organic dyes has been remarkably improved. An important approach on the design of organic sensitizers has been the structural variation of the compounds in order to obtain high energy conversion efficiency and long-term stability. |
