Abstract: A photoelectric conversion device and a method for producing a photoelectric conversion device are disclosed. The photoelectric conversion device includes a light-absorbing layer. The light-absorbing layer contains a chalcopyrite-based compound, and has a peak intensity ratio IB/IA in a range of 3 to 9, where IA represents a peak intensity of the peak formed by combining a peak of a (220) plane and a peak of a (204) plane in X-ray diffraction, and IB represents a peak intensity of a (112) plane.

Abstract: An apparatus for drying photo-sensitive material having a transfer path for the photo-sensitive material having at least one curved section, a supply device for supplying hot air to the photo-sensitive material, and a suction duct for sucking the hot air provided inside the curved section. The apparatus further includes turn rollers provided along the inside of the curved section, and a paper guide having an opening for circulating hot air, provided between the adjacent two rollers of the plurality of turn rollers in such a manner as not to contact with the photo-sensitive material. It is possible to dry all the portions of the photo-sensitive material under a uniform condition, while maintaining the transfer characteristics so that no drying irregularity appears; thereby, making it possible to prevent the reduction in the printing quality of the picture due to the drying irregularity.
