Synthesis of new di-anchoring organic sensitizer based on quinoxaline acceptor for dye-sensitized solar cells

摘要

New quinoxaline-based organic sensitizer bearing di-anchoring group for dye-sensitized solar cells (DSSCs) was synthesized from diethyl 4,5-diaminophthaltate, in which was prepared under mild condition by using Takehito’s method. The synthesized sensitizer was compared with mono-anchoring sensitizer through absorption spectra, emission spectra,J-Vcurve, and IPCE spectra, indicating the di-anchoring group leads to a noticeable improvement ofJscvalue owing to more efficient intramolecular charge transfer and channel number increment.
