PV Panel recycling technologies
Solar power is booming, with millions of metric tons of solar panels being produced each year. A panel has a projected lifespan of about 25 years, which means that today’s new solar farms will go out of service in the late 2040s. Most of the weight in a solar panel, about 75 percent, is glass, aluminum, with 10 percent; wiring in a junction box, at 5 percent; and silicon, with just 3.5 percent. Dedicated recyclers are needed, the authors write, to do a more thorough job of recycling all the components of a panel—including the crystalline silicon in the photovoltaic cells themselves. Silicon wafers account for about half the cost of a panel, as well as over half the energy and carbon footprint of manufacturing a panel. But silicon isn't currently being targeted for recycling much because the recovered silicon isn't pure enough to go straight back to a wafer manufacturer. Studies show that the impurity levels are an important issue during the recycling processes. The resulting
Lithium-ion Battery Future Trend
Lithium-ion battery is the core component of electric vehicles, grid trough periods of surplus electricity can be stored and used to drive an electric car, you can implement the strategy of low power instead of oil, reduce our demand for oil and improve urban air quality, battery store excess electricity during peak hours back to the grid can also achieve peaking. Once the grid has a strong ability to regulate the power of solar, wind, geothermal, ocean energy and other clean power generation means for generating intermittent easily into the grid, clean energy will gain large-scale applications, which solve mankind’s energy and environmental problems It will have a crucial role. Characteristics of the lithium-ion battery industry is the quantity, but the large scale, high technology and equipment of small, has a strong capability of independent innovation and even less, companies need to strengthen the capability of independent innovation, and actively participate in cooperative dev
