Battery Plates Saving Unpredictable Energy

- Aug 18, 2017 -

Following the advent of solar printers to greatly improve the efficiency of solar panels, the recent research team has invented the intention to improve the efficiency of solar panels results. At present, a professor at a university in the United States invented a transparent cooling coating that can improve the efficiency and durability of solar cells without affecting the solar panels to absorb sunlight and cool them. Mainly the use of silica photonic crystal coating material, this material is transparent to visible light, but has a strong thermal radiation. The use of this coating of solar panels can absorb the same amount of sunlight, while the temperature is reduced. This crystal is passive cooling, work does not need electricity, do not need any other energy input. Crystals can reduce the wafer temperature by 13 degrees Celsius. Simple to reduce the temperature of 13 degrees Celsius, but greatly improve the efficiency, can be increased by 1%.

The use of solar panels is very extensive, and this is only 1% improvement on the surface, but it saves unpredictable energy. Solar panel industry in the continuous progress, not only the reduction of technology costs, or work efficiency.

Solar panels are solar devices that absorb solar radiation and convert solar radiation directly or indirectly into electrical energy by photoelectric effects or photochemical effects. Most of the solar panels are "silicon", but the cost of production is So that it can not be used extensively and widely. Compared to ordinary batteries and recyclable rechargeable batteries, solar cells are more environmentally friendly green products

Monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be widely used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.

Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells). From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
