Abstract
Disclosed are an active layer composition for a solar cell containing a two-dimensional conjugated polymer that has excellent thermal/chemical stability and may improve power conversion efficiency of an organic solar cell via realization of high open-circuit voltage and short-circuit current, a preparation method of the composition, and an organic solar cell containing the composition. The composition contains a two-dimensional conjugated polymer having a repeating unit represented by a following Chemical Formula 4-2 as an electron donor material: wherein the Chemical Formula 4-2, n is an integer of 5 to 2000.
