The invention discloses a ternary random conjugated polymer based on 2,5-bis(2-thienyl)thiazolo[5,4-d]thiazolyl, which has the following general structure: By introducing 2,5-bis(2-thienyl)thiazolo[5,4-d]thiazole units, the band gap of the polymer was increased and the absorption spectrum was broadened; the introduction of 2,5-bis(2-thienyl)thiazolo The [5,4-d]thiazole unit has easily modified photophysical properties, and its terpolymer shows excellent photovoltaic performance; 2,5-bis(2-thienyl)thiazolo[5,4 ‑d]thiazole units are used in organic solar cells to improve the photoconversion efficiency of organic solar cells. |
