摘要： The present embodiments provide a flexible, lightweight and highly efficient photoelectric conversion device and further provide a manufacturing method thereof. The photoelectric conversion device according to the embodiment comprises a laminate structure of a substrate, an ITO electrode, a photoelectric conversion layer and a counter electrode. When subjected to surface X-ray diffraction analysis, the ITO electrode shows an X-ray diffraction profile characterized in that the peak at a diffraction peak position in the range of 2θ=30.6±0.5° has a half-width of 1.0° or less. The ITO electrode in the device can be formed by forming an amorphous-phase ITO film on the substrate and then by subjecting the film to annealing treatment at a temperature of 200° or less.
