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 a crimpable nanometer paper-based flexible solar cell by 3D aerogel jet printing. At first, that whole cellulose pap is soaked in an ionic liquid, A cellulose paper is rapidly partially dissolved and regenerated under hot pressing condition, nanometer paper with high transmittance and haze is prepared, As that flexible substrate material, the nanometer pap is sprayed on the surface of the flexible substrate material by 3D aerogel to jet the precision printing solar cell components including the anode PFN / Ag NWs, CuPc / C60 / PTCBI / BCP of that active lay, Cathode MoO3 / Ag / MoO3, The thickness of each component is precisely controlled by setting 3D printer parameters, and the surface electrode grid width of the prepared paper flexible solar cell is less than 10 microns and the thickness is less than 20 nanometers, so that the flexible organic thin film solar cell with 50-70% higher conversion efficiency than the traditional flexible solar cell isprepared.

Description

Technical field [0001] The invention relates to a method for preparing solar cells, in particular to a method for preparing flexible paper solar cells by 3D printing on the surface of flexible nano-optical paper with both high light transmittance and high haze; it belongs to new materials and new energy field. Background technique [0002] With the use of traditional fossil energy sources such as coal and oil, environmental pressures continue to intensify, fossil energy reserves are declining, and modern society’s energy consumption is rapidly increasing, causing energy costs to continue to rise. The development of more forms of clean energy has gradually become the survival of mankind. Urgent needs. However, currently 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 mainly focus on reducing manufacturing costs, improving solar cell transpare...
