Problems solved by technology

Traditional organic solar cells usually deposit solar cells on the surface of FTO or ITO. Although the conductive glass has excellent conductivity and good light transmittance, it does not have high haze and it is difficult to make full use of light, and because the conductive glass does not have nanometer The flexibility of optical paper limits the application of solar cells based on FTO or ITO
[0006] The traditional method of depositing solar cells requires the cooperation of spin coating, thermal evaporation, annealing treatment and etching, mainly due to the different dispersion and preparation conditions of the materials of each layer and the inability to uniformly deposit on the surface of the substrate during the preparation process. The process is relatively cumbersome and needs to switch processes, resulting in waste of materials and low efficiency

Abstract

The invention discloses a method for preparing rollable nano paper-based flexible solar cells by 3D airgel jet printing. In this method, ionic liquid is used to soak the whole cellulose paper, and the cellulose paper is rapidly partially dissolved and regenerated under hot pressing conditions to prepare nano-paper with high light transmittance and high haze. The surface of the solar cell is precisely printed by 3D airgel jetting. The components of the solar cell include the anode PFN / Ag NWs, the active layer CuPc / C 60 / PTCBI / BCP, Cathode MoO 3 / Ag / MoO 3 , the thickness of each component can be precisely controlled by setting the parameters of the 3D printer. The grid line width of the surface electrode of the prepared paper flexible solar cell is less than 10 microns, and the thickness is less than 20 nanometers. flexible organic thin film solar cells.

Description

technical field [0001] The invention relates to a method for preparing a solar cell, in particular to a method for preparing a flexible paper solar cell by 3D printing on the surface of a flexible nano-optical paper with high light transmittance and high haze; it belongs to new materials and new energy sources field. Background technique [0002] With the use of traditional fossil energy such as coal and oil, environmental pressure continues to intensify, fossil energy reserves decline, and energy consumption in modern society increases sharply, causing energy costs to continue to increase, and the development of more forms of clean energy has gradually become the key to human survival. Urgent needs. However, solar cells have not been widely used due to their high cost, low photoelectric conversion efficiency, and opacity. Therefore, the current research and development hotspots of solar cells are mainly focused on reducing manufacturing costs, improving the transparency o...
