Problems solved by technology

Although organic or polymer solar cells can be prepared in color, it is necessary to change the structure of the light-absorbing layer and reasonably match the energy levels of each functional layer of the battery, but the general energy conversion efficiency is low, and the synthesis of the light-absorbing layer The process is time-consuming and difficult to purify, so the commercialization of this type of colored solar cells is still a long way off
Some thin-film solar cells such as grating structure or double prism structure can also obtain colored patterned solar cell modules, but because the preparation process is relatively complicated, if you need to prepare patterned solar modules, you need the assistance of laser scribing. The energy conversion efficiency of color solar cells is generally low
Lay a patterned polymer film (such as colored polyethylene terephthalate film, polyvinyl chloride film, polycarbonate film and polystyrene film, etc.) on the surface of the packaged three-glass solar cell module, or use UV printing method, 3D printing method and other methods to prepare color film layer, after long-term use outdoors, the polymer will degrade after being exposed to light and rain, and the dyes, pigments and other substances on the surface will also decompose and be released into the environment Cause pollution, and color solar modules will fade, affecting the appearance

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, in particular to a patterned colored solar cell and a preparation method thereof. Background technique [0002] With the rapid development of the photovoltaic industry in recent years, the aesthetic requirements for building photovoltaic integration are also higher. The preparation of colored and patterned solar modules has also received extensive attention in recent years. Common methods for preparing colored solar cells are mostly based on preparing colored solar cells first and then encapsulating them. Since most of the materials suitable for building integration are glass substrates, due to its outdoor durability and light weight. However, glass is mostly transparent and colorless, so in order to change the appearance of colored solar cells, it is necessary to prepare the color of the cells themselves to be colored. Traditional solar cells such as crystalline silicon cells a...
