Charging or changing? It is difficult to break through the pain points of the construction of power exchange stations: the construction speed of power exchange stations is amazing. From August 2019 to December 2020, the number of power exchange stations has increased from 245 to 734 in more than a year. The top three operators are respectively Aodong, Weilai and Botan, 286, 175 and 94. The electric vehicle power change mode refers to the centralized storage, charging and distribution of a large number of batteries through a centralized charging station, and the battery replacement service for electric vehicles in the battery distribution station or the integration of battery charging, logistics allocation and power change services. However, the pain point of the power exchange mode is still the bottleneck that is difficult to break through.

In order to popularize the application in any industry, it is essential to continuously reduce the cost. This is especially true for photovoltaic enterprises that are still in the cold winter. Photovoltaic power generation was once very expensive, but driven by economies of scale, the cost of photovoltaic power generation has been declining in recent years, and now it is very close to parity. All this depends on the continuous innovation of photovoltaic technology. Theoretically, a 1 square meter sunlight exposure surface can generate 1000 watts of energy at most. If you want to increase the total reception of existing solar panels, you must focus the light, which will cause the panel to burn out due to excessive temperature.

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.

A foreign technology company has given a perfect solution: the solar cone they developed is composed of thousands of triangular solar panels. With a specially designed condenser and rotating cone, they can obtain 20 times more light than before, while maintaining the temperature of the core conversion components within a safe range, greatly improving the energy conversion efficiency. Industry insiders believe that this innovation has practical operational significance for photovoltaic power generation, but large-scale popularization still needs to consider the cost and further technical improvement.

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.
