摘要: Provided in the present disclosure is a photoelectric device. For the photoelectric device, a modification layer is added on the surface of a first electrode layer on the side away from a base substrate. The presence of the modification layer can prevent the direct contact of the first electrode layer and other film layers, thereby alleviating the problem of corrosion of indium-containing oxide which constitutes the first electrode layer. Furthermore, an indium-ion trapping group contained in the modification layer can fix indium ions released after the corrosion of the indium-containing oxide to the surface of the first electrode layer, thereby preventing the indium ions from moving to the inner part of the photoelectric device, which can then increase the service life of the photoelectric device.
