Current status and Prospect of photovoltaic and single polysilicon solar cells: Part 1 prediction of future development of crystalline silicon PK thin film silicon 1 crystalline silicon and thin-film solar cells in the next 3~5 years The second part is the development of GaAs, organic, dye sensitized, quantum dot and other photovoltaic cells Needless to say, renewable energy has become one of the hottest topics in recent years. This is because from the microscopic particles to the vast universe, or from lower bacteria to higher human beings, all changes and developments are inseparable from the role of energy. Most of the energy in the earth comes from the sun directly or indirectly. Solar cells are the direct conversion of solar energy to electricity. Non renewable energy and resources on the earth will be less and less, renewable energy will be more and more attention until the replacement of non renewable energy sources. The ultimate solution to the problem of human energy must be renewable energy (nuclear fusion is far from the present point of view, antimatter, vacuum, and other concepts more sci-fi! ). Compared with other renewable energy sources such as wind energy, tidal energy and geothermal energy, solar energy is relatively stable and widely distributed, and solar cells have also been extensively studied and commercialized. From the political point of view, Obama realized the urgency of developing renewable energy sources to get rid of the political threat of the petroleum exporting countries. To sum up, the development of renewable energy and the development of solar energy will be the only way for the sustainable development of mankind in the future. Figure
