The objective of the embodiments is to improve the peeling-resistance of a photoelectric conversion device. The embodiments relate to the photoelectric conversion device, a solar cell and a method for manufacturing the photoelectric conversion device. The photoelectric conversion device has a substrate, a bottom electrode comprising an electrode layer on the substrate and an intermediate interface layer, and a light absorbing layer on the intermediate interface layer. The intermediate interface layer is a compound thin film of a compound comprising Mo or W in the electrode layer and at least one element X selected from the group consisting of S, Se, and Te. The intermediate interface layer has a crystal phase and an amorphous phase with which the crystal phase is covered.
