摘要:Two organic quinoxaline dyes (WQ-1 and WQ-2) with a structure of quinoxaline-2, 3-diol as the electron withdrawing and anchoring group were synthesized and applied in the dye-sensitized solar cells. Fourier transform infrared spectroscopy and two other reference dyes (WQ-R1 and WQ-R2) without the hydroxyl groups were introduced to ascertain the adsorption properties of the dye series. The effect of the new electron acceptor and anchoring group on the performance of solar cells was investigated systematically. Under the standard light illumination (100 mW m(-2)), WQ-2 got an efficiency of 2.25%, with a short circuit photocurrent density of 5.51 mA cm(-2), an open circuit voltage of 0.612 V and a fill factor of 66.74%.
