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.

Intelligent product: compared with traditional fuel vehicles, what is the core competitiveness of new energy vehicles? Intelligence seems to be the accepted answer. The reporter's visit found that more and more new energy vehicle enterprises have built a service system for the whole process of users' purchase and use of vehicles through the digital platform, and improved the digital life and after-sales service in the vehicle. From the perspective of configuration and performance, the new energy models of the three enterprises visited by the reporter have been able to achieve multiple functions such as car control, service and social networking with the help of the car machine system and APP, and the software upgrade and function iteration optimization can also be carried out after the car is sold, so as to realize the constant use and freshness of the car.

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.

There are four main pain points: A. Battery standardization is too difficult. The separation of vehicle and electricity first requires the standardization of power batteries, BMS standardization, interface standardization, and software management standardization. Any vehicle upgrade must be compatible with the previous generation of products. Battery standardization is too difficult. Every car company wants to make its own electricity exchange standard. It is unrealistic for so many car companies to unify. B. The investment is large and the cost is high. The replacement of power needs to lay a large network, and the investment scale is far greater than charging. Build a power exchange network for a city to provide special tram exchange services. The cost can be recovered only after at least 6-8 years or even more. C. The deflagration hazard of the power plant is large, and the safety hazard is huge. D. It is difficult to improve the customer experience.
