The research progress of porphyrin dye sensitizers

Dye-sensitized solar cell has a low price, simple fabrication process and high photoelectric conversion efficiency, attracting widespread attention. As the key part of dye-sensitized solar cells, sensitizer plays a significant role. Porphyrin compounds have strong absorption in visible region and are easy to modify, which have been extensively and thoroughly researched. This paper introduced the structure, and fundamental of DSSC, the developments of porphyrin dyes and the impact of structural changes of porphyrin derivatives on the optical properties in recent years. The co- sensitization ofporphyrin sensitizers and other sensitizers demonstrates that the expansion of dye absorption range in the visible region might be an effective way to improve the photoelectric conversion efficiency.
