Abstract

The invention discloses a light-absorption material and an application thereof in the preparation of a 3D printing solar cell panel. The light-absorption material comprises the following raw materialsby weight: one part of graphene, 76 parts of gallium arsenide, 9 parts of bismuth oxide, 12 parts of bismuth oxide, 10 parts of titanium oxide, 6 parts of zinc oxide, 5 parts of propyltrimethoxysilane, 7 parts of dioctyl phthalate, 3 parts of polyaluminum chloride, and 2 parts of a 701 powder enhancer. The 3D printing solar cell panel comprises a substrate and a plurality of light absorbers, wherein all the light absorbers are distributed on the same surface of the substrate in an attached manner. The bottom of each light absorber is shaped like a polygon, and each polygon is provided with aninclined surface which forms a camber with a horizontal plane. The inclined surface is provided with an elliptical bulged part. The surface of the solar cell panel is made into a plurality of butterfly-shaped bulged bodies in a mode of 3D printing manufacturing, so the surface radiation of light energy can be converted into electric energy, and the absorption efficiency is improve by one time ormore.

Description

【Technical field】 [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a light-absorbing material and its application in preparing 3D printed solar panels. 【Background technique】 [0002] With the deepening of the global energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, the energy crisis of the century, global power shortages, and power outages in many areas have brought a lot of inconvenience to our lives. The rising prices of traditional petrochemical energy such as oil and coal and their impact on the global climate and environment during the combustion process have attracted increasing attention, which has forced the world to focus on the development of new energy. From the perspective of resources, environment, and social development needs, it is an inevitable trend to develop and utilize new and renewable energy. In the family of new energy and rene...
