High efficiency and stable dye-sensitized solar cells with an organic chromophore featuring a binary -conjugated spacer

Guangliang Zhang, Hari Bala, Yueming Cheng, Dong Shi, Xueju Lv, Qingjiang Yu and Peng Wang

We employed a binary spacer of orderly conjugated 3,4-ethyldioxythiophene and thienothiophene to construct a wide-spectral response organic chromophore for dye-sensitized solar cells, exhibiting a high power conversion efficiency of 9.8% measured under irradiation of 100 mW cm-2 air mass 1.5 global (AM1.5G) sunlight and an excellent stability.
