A strategy to design highly efficient porphyrin sensitizers for dye-sensitized solar cells

摘要

We designed highly efficient porphyrin sensitizers with two phenyl groups at /weso-positions of the macrocycle bearing two orftho-substituted long alkoxyl chains for dye-sensitized solar cells; the erf tho-substituted devices exhibit significantly enhanced photovoltaic performances with the best porphyrin, LD14, showing J_(sc) = 19.167 mA cm ~(-2) V_(oc) = 0.736 V, FF = 0.711, and overall power conversion efficiency n = 10.17%.
