MIT scientists have developed a glass coating that can concentrate solar energy
people usually install a large-area battery panel on the roof to collect solar energy. But this method is expensive and inefficient. Now, as long as a layer of coating is added to the ordinary glass window, solar energy can be collected and supplied, and the produced non phthalates have good kink resistance, excellent weldability, transparency and flexibility, which affect the lighting
scientists at the Massachusetts Institute of technology developed this technology. However, when the ultraviolet wavelength reaches more than 380 nm, they mix at least two kinds of coatings in a special proportion to make an energy gathering material to absorb light of various wavelengths. After installing solar cells on the edge of the glass, apply the mixed paint on the surface of the glass. After absorbing the sunlight, the paint will transmit the light at different wavelengths to the solar cells installed on the edge of the glass
this kind of energy accumulating material is not only suitable for glass, but also for materials such as plastic plates. We should check whether the universal experimental machine has a problem of circuit storage.
mark, electrical engineer and head of the research group at MIT Bardo said, "the coating can collect sunlight on large-area objects, such as glass windows, and then transmit it to the solar cells at the edge of the pane."
this paint can be made into color or transparent and colorless. When painted on the glass window with transparent color, it will not affect the daylighting
at present, most solar concentrators use large mobile mirrors to track sunlight and produce high light intensity. However, the cost of configuration and maintenance of large mobile mirrors is quite high, and the whole device is huge, which wastes space. The advent of new energy gathering technology has solved these problems
because the production process of this technology is not complex and the material cost is not expensive, researchers believe that within three years, it will be widely used and occupy a place in the market. In addition, this technology can also be added to the existing solar panels, which is not expensive, but can improve the efficiency by nearly 50%
bardo said, "we think it is a practical technology with stable performance and easy molding in the laser sintering process. It greatly reduces the cost."
