Application of Cu(ii) and Zn(ii) coproporphyrins as sensitizers for thin film dye sensitized solar cells

We synthesized the Cu( ii ) and Zn( ii ) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21 H ,23 H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper( ii ) coproporphyrin-I exhibits a power conversion efficiency o...

Description
Summary:We synthesized the Cu( ii ) and Zn( ii ) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21 H ,23 H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper( ii ) coproporphyrin-I exhibits a power conversion efficiency of 3.8% measured under irradiation of AM 1.5G full sunlight (100 mW cm −2 ). Here we report Cu( ii ) and Zn( ii ) coproporphyrins (see Figure) and employed them as sensitizers in dye-sensitized solar cells.
