A strategy to design highly efficient porphyrin sensitizers for dye-sensitized solar cells
2011
We designed highly efficient porphyrin sensitizers with two phenyl groups at meso-positions of the macrocycle bearing two ortho-substituted long alkoxyl chains for dye-sensitized solar cells; the ortho-substituted devices exhibit significantly enhanced photovoltaic performances with the best porphyrin, LD14, showing JSC = 19.167 mA cm−2, VOC = 0.736 V, FF = 0.711, and overall power conversion efficiency η = 10.17%.
