Shen Hui: Solar crystalline silicon cells dominate in the future
Solar energy is a clean and renewable new energy source. Light energy is a magic weapon to meet the global power demand in the future. The growing shortage of environmental issues such as energy shortages has made solar cells a renewable energy source.
At present, solar cells are dominated by crystalline silicon cells, and thin-film batteries are also rapidly developing. The facts show that crystalline silicon is the most convenient PV technology because it draws on the process technology in the microelectronics field to use crystalline silicon to produce stable and efficient solar cells. The technology has a market share of about 90%, and the polysilicon battery market share has exceeded 80%. The photoelectric conversion efficiency of single crystal silicon can reach more than 22%.
Sun Yat-sen University Professor Shen Hui
On August 26, at the inaugural meeting of the Shenzhen New Energy Industry Association, Professor Shen Hui of the famous Institute of Solar Energy at Sun Yat-sen University published a special report on “Review and Prospect of Photovoltaic Developmentâ€: “Crystalline silicon cells will be even more in the next 10 years. For a long period of time, photovoltaic products will not change, and crystalline silicon cells will continue to develop. Thin-film solar cells are also worthy of attention but have not yet been able to compete with crystalline silicon cells.â€
Photovoltaic BIPV has always been the most important application field and the most important market in the world photovoltaic power generation. Professor Shen said that in the combination of cities and buildings, every building can effectively use solar energy in the future. Both solar photovoltaic power generation and solar thermal power generation will be greatly developed, but in the cities, photovoltaic power generation will be an optimal solution.
Professor Shen also pointed out: "The next decade is the growth period of photovoltaic power generation. Photovoltaic power generation will be an important form of energy after 2020 and is expected to account for 5%-10% of the electricity share in developed countries."
The current rapid development of the solar photovoltaic industry is a benign development trend, and the outlook is bound to be excellent. Although the reduction of PV subsidies in the second half of 2010 led to the release of demand in the first half of the year, other market demands are also expected to accelerate growth. In the medium to long term, the solar energy industry will maintain strong demand, and the overall PV industry's market outlook remains optimistic.
The led rgb flood light is made of aluminum alloy die-casting and electrostatic spraying surface treatment. The coating is resistant to high temperature, acid and alkali, and anti-aging. The lamp body adopts the integrated design of light source and electrical appliances, with compact structure and small volume.
The reflective surface is designed to form various required light distribution, with high luminous efficiency and low light source glare. The lamp head is made of tempered glass, which is safe, high temperature resistance, high strength and good light transmission. The sealing strip is an anti-corrosion silicone rubber sealing strip, which has good sealing performance and is suitable for waterproof and dustproof applications.
You can control the color change of the led floodlight rgb through a mobile phone to achieve all color spectrums and be used in various places. Due to its convenience and full spectrum lighting, rgb Led Flood Light can be used as outdoor LED flood light for Christmas, Halloween lights festivals.
