摘要：

Two organic sensitizers(LI-33 and LI-34) with double anchoring units were synthesized and utilized for dye sensitized solar cells(DSSCs), which contained thiophene or vinyl thiophene as π-bridge. The introduction of double anchoring units can change their absorption spectra and energy levels in a large degree, thus, the better light-harvesting ability and the convenient electron transfer along the whole molecule can be obtained. The solar cell based on LI-34 exhibited a broad incident photonto-current conversion efficiency(IPCE) spectrum and high conversion efficiency(η=6.05%) with coadsorbent CDCA.
