Abstract

The present invention belongs to the technical field of polymer solar cell preparation, and discloses a polymer solar cell and a preparation method thereof. The solar cell has a layered structure, and comprises a substrate, an anode layer, an anode modification layer, a photoelectric active layer, a cathode modification layer and a cathode layer. The substrate is made of glass. The anode layer is made of indium tin oxide. The anode modification layer is made of PEDOT: PSS. The photoelectric active layer is made of composite material of porous graphene / poly(p-phenylene vinylene). The cathode modification layer is made of lithium fluoride. The cathode layer is made of metal aluminium. According to the invention, graphene is used as a carrier to bear poly(p-phenylene vinylene), such that the conductivity is improved; and poly(p-phenylene vinylene) is used for preventing the agglomeration of the grapheme layer, thereby increasing the specific surface area of grapheme. Thus, a solar cell with a photoelectric conversion rate of up to 3.67% is prepared.

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to a polymer solar cell and a preparation method thereof. Background technique [0002] Facing the severe challenges of the gradual decrease of world energy and the gradual increase of human energy demand, the development of new energy and new energy storage devices has become one of the effective ways at present. Among them, solar energy, as a renewable and clean energy source, has developed rapidly in today's "low-carbon, environmentally friendly and green" environment. At the same time, solar cells, which convert solar energy into electricity through the photovoltaic effect, are also developing rapidly. The current research hotspot is how to prepare solar cells with excellent performance, simple preparation, safe use and low cost (WanXJ, LongGK, HuangL, et al. . [0003] Solar cells include polymer solar cells, dye-sensitized solar cells, and silicon...
