Problems solved by technology

[0008] Thin-film solar cells have the characteristics of lightness, portability, and high conversion efficiency, and are easy to combine with various products, but the conversion efficiency is low, and the high conversion efficiency of solar panels means that your solar panels will be smaller and still produce same power output
In order to obtain high-efficiency lightweight components, the chip still needs to use crystalline silicon cells, and usually use a substrate with a lower pass density instead of glass. The processing of solar products includes high-temperature hot pressing, so the temperature resistance of lightweight substrates is required Extremely high, material options are very limited, increasing material cost and processing difficulty

Abstract

The invention provides a lightweight solar power generation panel and a preparation method thereof. The lightweight solar power generation panel includes a substrate, an insulating layer, a battery layer and a support layer which are sequentially stacked; the materials of the substrate include polypropylene, polychlorinated Any one or a combination of at least two of ethylene, polyethylene, polymethyl methacrylate, polycarbonate, polystyrene or acrylonitrile-butadiene-styrene copolymer. The lightweight solar power generation panel provided by the invention adopts low-density substrate material, which makes the whole solar power generation panel lighter and more portable.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a lightweight solar power generation panel and a preparation method thereof. Background technique [0002] Solar energy refers to the thermal radiation energy of the sun, and its main manifestation is the sun's rays that are often said. In modern times, it is generally used to generate electricity or provide energy for water heaters. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power is a new type of renewable energy. [0003] Single solar cells cannot be used directly as a power source, so solar photovoltaic modules are derived, which are connected in series or in parallel through several single cells, and then packaged to form solar photovoltaic modules. Solar photovo...
