Abstract: The present disclosure relates to a ternary photoactive layer composition and an organic solar cell including the same. According to the present disclosure, excessive crystal growth and aggregation can be prevented during large-area coating of a photoactive layer, uniform morphology can be achieved without significant phase separation, an organic solar cell with superior photovoltaic cell characteristics can be realized, and superior performance may be maintained even after long-term exposure to heat by preventing the morphological change of the photoactive layer.
