Abstract

The invention discloses a VCM thin film for solar light concentration and application thereof and a solar photovoltaic cell. The VCM thin film for solar light concentration sequentially comprises a surface hardening coating, a transparent film layer, a light transmittance enhancing coating, a vacuum metallization clad layer, an adhesive layer and a base film layer. The surface hardening coating is a polyurethane ultraviolet curing coating with the hardness which is equivalent to more than pencil hardness 2H and the thickness of more than 0.8 mm. The VCM thin film for solar light concentration in the invention is low in cost, high in solar radiation energy and reflecting efficiency, and is capable of greatly reducing the usage amount of solar photovoltaic cell packs and thus the cost is saved. Simultaneously, the manufacturing cost of the VCM thin film for solar light concentration is obviously much lower than that of similar products, and the VCM thin film for solar light concentration has very wide application prospect.

Description

technical field [0001] The invention relates to a VCM thin film for solar energy concentration and application thereof, and also relates to a solar photovoltaic cell containing the VCM thin film. Background technique [0002] Solar energy is an inexhaustible resource. The advantage of solar energy is that it is free and does not produce greenhouse gases. Compared with other forms of renewable energy such as wind energy, solar energy is the most abundant and stable energy source. Using solar energy to generate cheap electricity is one of the key topics in new energy research. There are two main methods: one is to convert solar energy into thermal energy to generate electricity, and the other is photovoltaic power generation. Photovoltaic power generation has developed a variety of semiconductor photovoltaic cells such as silicon and gallium arsenide. The most widely used. [0003] At present, monocrystalline silicon / polycrystalline silicon photovoltaic cells mainly use the...
