At present, solar cells are divided into several types according to the raw materials, structures and manufacturing methods used. Among them, crystalline silicon solar cells mostly refer to monocrystalline silicon solar cells and polycrystalline silicon solar cells using silicon semiconductor substrates as raw materials; In addition, there are amorphous silicon solar cells, which are made by evaporating amorphous silicon on glass substrates rather than silicon substrates based on the same film preparation method as liquid crystal panels. Monocrystalline silicon solar cells form solar cells on monocrystalline silicon substrates, and there are also products with conversion efficiency up to about 20%, which have excellent performance and reliability. However, the price of silicon substrate as raw material is expensive, and the power generation cost per watt is high. Although the conversion efficiency of polycrystalline silicon solar cells is lower than that of monocrystalline silicon solar cells, they have the advantage of relatively low cost.

The charging pile industry comes with the development of new energy vehicles. In 2020, the charging pile will be included in the new infrastructure and written into the government work report, which will become the precondition for developing new energy vehicles, stimulating new consumption demand and helping the industry upgrade. Under the exploration of new business model and the guidance of a new round of policies, new channels for the development of charging piles have been opened, ushering in new opportunities. The charging pile industry chain is divided into supply terminals such as equipment manufacturers and power suppliers, operation terminals such as operators and new energy vehicle enterprises, and support terminals such as map navigation and payment functions. The core link is the operation end, which is responsible for the investment, construction and operation management of the charging pile. At present, Chinese funded enterprises, private capital and vehicle enterprises are all involved in the operation.
