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: 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: Disclosed is an electron transport layer for a flexible perovskite solar cell. The electron transport layer includes transition metal-doped titanium dioxide particles. The titanium dioxide particles are densely packed in the electron transport layer. The electron transport layer is transparent. The use of the electron transport layer enables the fabrication of a flexible perovskite solar cell with high power conversion efficiency. Also disclosed is a flexible perovskite solar cell employing the electron transport layer.
