Solar cells have been widely used in communications, transportation, and civilian products. Photovoltaic power generation is not only included in the national research plan, but also included in the national power construction plan, and also applied in some major engineering projects. Photovoltaic power generation has spread throughout the provinces and autonomous regions of western China, as well as some provinces, municipalities and autonomous regions in the central and eastern regions, with a total investment of more than 3 billion yuan.
The high efficiency and low price of solar cells has always been the goal of international development. In the same way, the fundamental problems of the production and promotion of Chinese products are also gathered here. The demand for electricity-free areas such as grasslands, islands, and deserts is huge, but the problems of affordability, insufficient production scale, and weak product targeting are very prominent. In the urban power system, the high one-time investment cost is undoubtedly more difficult to promote. Therefore, improving efficiency, reducing costs, and expanding scale should be the subject of today's development and production of solar cells.
