Abstract

The invention discloses a method for preparing DSC light anode scattering layer slurry, which comprises: firstly, adding ethyecellulose into terpinol according to a mass ratio of 1:(5-7), stirring for 2 hours in a water bath at the temperature of 80 DEG C to obtain an organic carrier with a viscosity of 6.0 to 6.1cp; and secondly, mixing anatase TiO2 with a particle size of 4 mu m and TiO2 with a particle size of 100 to 200 nanometers in a mass ratio of 1:(5-9), placing in an agate mortar, adding the organic carrier, and fully grinding for 1 hour. A battery made by using the light anode scattering layer slurry prepared by the method is improved by over 20 percent in photoelectric performance and has a remarkable application effect.

Description

technical field [0001] The invention belongs to the technical application field of solar cells, in particular to a method for preparing DSC light anode scattering layer slurry. Background technique [0002] As a new energy source, solar energy has been paid more and more attention by various countries under the environment of global warming. At present, crystalline silicon solar cells are widely used and have become the main market for solar cells. However, there are inherent weaknesses in crystalline silicon solar cells: 1. The band gap Eg of silicon materials is Eg=1.12eV, and the theoretical efficiency of solar photoelectric conversion is relatively low; 2. Silicon materials are indirect energy band materials. The light absorption coefficient is much lower than that of other solar photovoltaic materials, so the crystalline silicon material needs to be purified many times, so the cost is relatively high. Therefore, thin-film solar cells have aroused people's interest and...
