With the continuous development of human society, the contradiction between man and nature is becoming more and more prominent. At present, the most prominent problem facing the world is environment and energy, that is, environmental deterioration and energy shortage. Of course, this problem should be handled through the correct countermeasures taken by governments all over the world. The development of new materials and corresponding technologies will be the most effective way to solve this problem. In fact, in recent years, people have shown a positive and effective role in the development and utilization of solar materials. The development of this new functional material can solve the energy shortage faced by mankind without causing environmental pollution. Although the cost of solar materials is still high and the performance needs to be further improved, with the continuous progress of material science, solar materials show more and more attractive development prospects. It can be predicted that solar materials will play a more important role in the next century. Just as the development of functional materials such as semiconductors has brought about the rise and development of telecommunications and computer industry, solar materials and related technologies will also bring about the development of industrialization of solar devices, so as to achieve a more perfect level of human harmony in environmental protection and energy utilization. Solar energy is an inexhaustible renewable energy and clean energy, which does not produce any environmental pollution. In order to make full and effective use of solar energy, people have developed a variety of solar materials.
For 4 juncion , The newly developed four-junction solar cell is made of different III-V group (group III B, Al, Ga, In and V group N, P, As, Sb, etc. in the periodic table of elements) semiconductor materials As a result, these nodes are stacked layer by layer, and a single sub-cell can absorb light of different wavelengths in the sunlight spectrum.
1) Toughened glass is used to protect the main body of power generation
2) EVA is used to bond and fix toughened glass and power generation main body
3) The main function of solar cells is power generation.
4) Backplane function, sealing, insulation and waterproof
5) Aluminum alloy protective laminate plays a certain role in sealing and supporting.
6) The junction box protects the whole power generation system and plays the role of current transfer station.
