    摘要： An organic solar cell device is provided, including a first electrode (10), a photoactive layer (20), a hole transport layer (30), and a second electrode (40) that are stacked successively. The photoactive layer (20) includes an electron receptor material and an electron donor material. The electron receptor material is graphene nitride that forms a foamy film on the first electrode (10) and has a unit network structure. A part of the electron donor material permeates into the graphene nitride, and a part of the electron donor material is enriched on a side of the hole transport layer (30) to form an electron donor enriched layer (21). The graphene nitride and the electron donor material form a bulk heterojunction structure. The first electrode (10) is conductive glass, and the second electrode (40) is a metal electrode. The solar cell device uses the graphene nitride as the receptor material, so that the graphene nitride and an organic donor material better form an interpenetrating network structure, thereby facilitating charge separation. In this way, an open-circuit voltage is ensured, a short-circuit current is enhanced, and energy conversion efficiency of the solar cell is improved. A method for preparing an organic solar cell device is further provided.
