摘要：
We have prepared a series of novel diphenylpyran derivatives as photosensitizers of dye-sensitized solar cells (DSSCs) for the first time. Nonsubstituted dye 3a shows an energy conversion efficiency of 2.3% and iodine-substituted dye 3d shows a higher efficiency of 2.9% due to the tuned energy levels and steric effect.
