摘要
Three new multi-carbazole derivatives (2C-4C) with a twisted and zigzag-shape structure were designed, synthesized and used as sensitizers for dye-sensitized solar cells (DSSCs). The results showed that this non-planar structure of 2C-4C, combined with multi alkyl chains, can efficiently inhibit dye aggregation and charge recombination, which gave DSSCs with a high open circuit voltage (V-oc) and an overall solar-to-electric conversion efficiency (eta) of up to 6.33%.
