Abstract

The invention discloses an inverted polymer solar cell with a silver nanowire / ZnO laminated layer as an electronic collection layer and a manufacturing method thereof, with the purposes of using scattering of the silver nanowires and plasma resonance effects to enhance the light absorption capacity of an active layer in the solar cell, improving the photoelectric conversion efficiency of the polymer solar cell, solving the problem of accumulation when a silver nanowire thin film is manufactured by using a spin coating method or a spraying method, and thus reducing the surface roughness of the silver nanowire thin film and short circuit of a cell device. The manufacturing method realization process comprises steps: a dip-coating method is adopted to form an ordered silver nanowire thin film on ITO, a ZnO layer coats the silver nanowire layer through spin coating or dip-coating to acquire a silver nanowire / ZnO laminated layer, the silver nanowire / ZnO laminated layer serves as an electronic collection layer to manufacture the inverted polymer solar cell, and the photoelectric conversion efficiency of the cell device is improved.

Description

technical field [0001] The invention relates to the technical field of organic solar cells, in particular to an inverted polymer solar cell with a silver nanowire / ZnO stack as an electron collection layer and a preparation method thereof. Background technique [0002] In recent years, emerging solar cell technologies have emerged, among which, compared with inorganic semiconductors, the light absorption and carrier transport layers of organic polymer solar cells have both the processability and flexibility of polymer materials and the advantages of semiconductor materials. Conductivity, can be prepared by wet methods such as spin coating, coating, inkjet printing, screen printing, roll-to-roll printing; in addition, the substrate of the battery can be made of flexible materials coated with transparent electrodes, which makes it It has broad prospects for large-area flexible preparation. However, its conversion efficiency is relatively low compared with mature inorganic sola...
