Abstract: Disclosed is a conjugated polymer for an organic solar cell. The proportion of units containing no alkyl thiophene moieties in the conjugated polymer can vary to make the conjugated polymer suitable for use as an electron-donating organic semiconductor material in a small-area or large-area organic solar cell. Therefore, the use of the conjugated polymer ensures high energy conversion efficiency of the organic solar cell.
