Abstract: An organic solar cell is provided. The organic solar cell includes a photoactive layer in which a low molecular weight conjugated compound as a first organic semiconductor material is mixed with an appropriate amount of a second organic semiconductor material. The first organic semiconductor material includes both electron donors and electron acceptors. The presence of the electron donors and the electron acceptors in the first organic semiconductor material improves the morphology of the photoactive layer, leading to high efficiency of the organic solar cell.

Abstract: A self-healing conjugated polymer is disclosed. The self-healing conjugated polymer has hydrogen bonding functional groups introduced into its side chains. Due to this structure, the conjugated polymer is imparted with the ability to recover through self-healing while maintaining its inherent properties (for example, physical and electrical properties). Based on this effective self-healing ability, the conjugated polymer is expected to find application as a biomaterial, a pharmaceutical material, a nonlinear optical material or an organic electronic material.
