Abstract: A Cu2ZnSnS4-xSex (0≦x≦4) thin film solar cell is disclosed. The thin film solar cell includes a Cu2ZnSnS4-xSex (0≦x≦4) thin film as an absorber layer produced by forming a precursor film composed of Cu, Zn, Sn, and Se using an ionic liquid as a solvent through a constant current process and annealing the precursor film with sulfur. Also disclosed is a method for fabricating the thin film solar cell. The method uses a non-vacuum electrodeposition process that is appropriate for large-area mass production and is thus cost effective compared to a vacuum process. In addition, since the method uses an ionic liquid, the formation of by-products harmful to humans as a result of side reactions is suppressed. Furthermore, the method uses a one-step electrodeposition process, which enables the deposition of a maximum of four elements at one time, or a multi-step deposition process, and an annealing process.

Abstract: A conjugated polymer that is an electron donor, that is soluble without aggregation, that is solution-coatable and is dryable at a temperature below 70° C., that has an energy conversion efficiency of 7 % or more over an area of 5 cm2 or more, and that is composed of a repeating unit represented by Chemical Formula 1A below: where x is a real number from 0.1 to 0.2; and n is an integer from 1 to 1,000. The conjugated polymer forms a uniform thin film over a large area of, for example, an organic solar cell, without a heat treatment due to superior solubility and crystallinity at low temperature and, thus, allows fabrication of an organic solar cell with high efficiency at a low temperature.

Abstract: An organic solar cell includes a substrate; a first electrode; a second electrode disposed opposite the first electrode; a photoactive layer that is disposed between the first electrode and the second electrode, and that comprises n-type organic semiconductor material and p-type organic semiconductor material; and an intermediate layer that is disposed on at least one surface of the photoactive layer and that contains a compound represented by Formula 1 below: where R1, R2, R3, R4, R5, and R6 are each independently selected from the group consisting of hydrogen atoms, a carbonyl group, a hydroxyl group, a nitro group, an amino group, a sulfonyl group, a phosphoryl group, straight-chain or branched C1-C7 alkyl groups, and straight-chain or branched C8-C20 alkyl groups, wherein R1, R2, R3, R4, R5, and R6 are not all the same. The organic solar cells have enhanced photostability due to introduction of the intermediate layer.

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.

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.
