The invention discloses a dye photosensitizer containing a biscarbazole group and a preparation method thereof for dye-sensitized solar cells, including pure organic small molecule dyes containing a biscarbazole group and ruthenium-based complex dyes . The raw materials of this kind of dyes are cheap and easy to obtain, and the synthesis is simple. Among them, the ruthenium-based complex dyes can effectively improve the open-circuit photovoltage of solar cells, and the highest energy conversion efficiency is higher than 8%, and the performance is better than the standard dye N3; while pure organic small molecule dyes Does not contain precious metals, low cost and less environmental pollution. |
