Analysis of the development trend of solar cell industry
Solar energy is both primary energy and renewable energy. It is rich in resources and can be used free of charge without transportation and without any pollution to the environment. However, solar energy also has two major drawbacks: one is the low energy density; the other is that its intensity cannot be maintained constant due to various factors (season, location, climate, etc.). These two major drawbacks greatly limit the effective use of solar energy.
In the past ten years since the beginning of the 21st century, the development and industrialization of the world's crystalline silicon solar energy battery has achieved a series of new achievements and breakthroughs. The highest photoelectric conversion efficiency of the high-efficiency monocrystalline silicon solar cell laboratory has reached 24.7%, and the highest photoelectric conversion efficiency of the high-efficiency polycrystalline silicon solar cell laboratory has reached 20.3%. At the same time, the world's leading universities and research institutions have entered the field of solar energy, and advanced technologies continue to spread to the industry, which has continuously improved commercial battery technology and greatly reduced the cost of solar photovoltaic power generation. Technological advancement has become an important factor in reducing the cost of solar photovoltaic power generation and promoting the development of the crystalline silicon solar cell industry and market.
The future development trend of the solar cell industry is:
1. Development of photovoltaic manufacturing to automation, intelligence and flexibility
With the continuous advancement of product technology and manufacturing processes, photovoltaic manufacturing will be closer to the precision manufacturing of semiconductors, and the degree of product integration is higher. In the future, efficiency and reliability are not the only indicators for measuring photovoltaic products. Intelligent, lightweight, and architectural requirements will make products more diversified, suitable for a variety of applications and installation conditions, to achieve energy Internet. The automation, intelligence, flexibility and future global virtual factories of photovoltaic manufacturing are the main trends in the current industrial upgrading.
Second, the market application continues to expand, reducing costs is still the industry theme
The application of solar photovoltaic market will show a wide range of fields and diversified trends. Photovoltaic products that meet various needs will continue to emerge. In addition to large-scale grid-connected photovoltaic power plants, photovoltaic power generation systems, small-scale photovoltaic systems, and off-grid photovoltaic systems combined with buildings Etc. will also rise rapidly. The cost of solar cells and photovoltaic systems continues to decline and approach the cost of conventional power generation. It will continue to be the theme of the development of the photovoltaic industry. From silicon materials to components and supporting components, the market pressure of rapid price reduction will be faced, and solar cells will continue to be highly efficient. Development in low cost direction.
