Progress of Porphyrin Sensitizers for Dye-Sensitized Solar Cells

As a core structure of nature photosynthesis, porphyrin has good light, thermal and chemical stability. In the past two decades, porphyin based dye-sensitized solar cells (DSSC) has attracted much attention relevant to global environmental issues. Up to date, they exhibit the best performance with a benchmark efficiency of 13% reported in 2014 for dye-sensitised solar cells. The progress of porphyrins and their derivatives applied in DSSC from the point of view of molecular engineering design correlated with photovoltaic performance is systematically summarized.
