Pyrazino[2,3-g]quinoxaline dyes for solar cell applications†
Abstract
Pyrazino[2,3-g]quinoxaline was first employed as a π-linker in D–π–A type dyes, exhibiting an unusually broad and intense spectral absorption ranged from the visible to the near infrared region. A power conversion efficiency of 6.86% was achieved in dye-sensitized solar cells.
