Abstract

An organic dye and preparation method thereof and dye-sensitized solar cells using this organic dye are provided. The structure of the organic dye molecule is donor-conjugated unit(s)-acceptor. The organic dye with broad spectrum response and high molar-absorption coefficient is obtained by modifying the structure by using various conjugated unit(s) in combination with donor and acceptor. The conditions of preparation of the organic dye are mild and the yield is high, and the organic dye can be used for highly effective dye-sensitized solar cells.
