Abstract

The invention relates to a solar photoelectric conversion coating and a preparation method thereof. The solar photoelectric conversion coating is composed of P-type conductors, N-type conductors, liquid epoxy resin, emulsifiers, curing agents, additives, and electrode lead wires. The specific technical scheme is: after grinding the P and N type conductors, carry out surface modification treatment, add liquid epoxy resin, emulsifier, curing agent to the homogenizer for dispersion treatment, and then spray dry to obtain water-soluble epoxy resin Paint powder. When in use, the paint is dissolved in water, coated on the surface of the object, connected to the inner and outer layers of the coating with electrode leads, and under sunlight, a potential difference can be formed in the PN junction of the paint to generate electric energy. Due to the bending flexibility of the coating, it is convenient to use, widens its application field, and has extensive market value.

Description

technical field [0001] The invention relates to a coating, in particular to a coating capable of absorbing solar energy and converting it into electric energy, and belongs to the field of energy-saving coatings. Background technique [0002] With the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent, and new energy and renewable energy have become one of the most decisive technical fields in the development of the world economy in the 21st century. Photovoltaic battery is an important renewable energy, which can be used as an independent energy source or realize grid-connected power generation with zero pollution emission. Due to the dual pressure of the reduction of non-renewable energy and environmental pollution, the photovoltaic cell industry is developing rapidly. [0003] At present, solar cells are mainly divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amor...
