Color coating, photovoltaic module with color coating and preparation method of photovoltaic module

Abstract

The invention relates to a color coating. A precursor solution containing a color pigment is coated or deposited on an attachment, and then annealing is performed, wherein the precursor solution contains a solvent, color nanoparticles and an additive. The invention further discloses a photovoltaic module using the color coating and a preparation method of the photovoltaic module. The stable colorcoating is formed on the structural layer of the photovoltaic module, the inherent color of the photovoltaic module is changed, the attractive requirement of the photovoltaic module is met, the photovoltaic module has high light stability, corrosion resistance, abrasion resistance and heat stability, and meanwhile the photovoltaic efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic cell preparation, and in particular relates to a color coating, a photovoltaic module with the color coating 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. Preparation of colored solar photovoltaic 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. Most of the materials suitable for building integrated photovoltaics are glass substrates because of their 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 colore...

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
