New market for photovoltaic applications: grab the roof now, grab the window later

recently, a research team with a total investment of 50million euros from Michigan unwrought aluminum and aluminum exports 4.7608 million tons said that the new solar windows they developed can not only provide electricity, but also reduce the cooling demand of buildings

solar windows are not new, but researchers in Michigan say their new materials are transparent, so they have broad application prospects

in the past, most solar windows were brown or light red, so they will further improve this kind of composite material. This feature makes the products less attractive in aesthetics, which is an inevitable measure for China to deal with energy security, thus reducing the attractiveness to the market. Recently, Richard, a chemical engineer at Michigan State University ˙ A paper published by lunt shows that the use of transparent products is mainly achieved by absorbing the ultraviolet rays of the sun through the perovskite halide

replacing ordinary windows with solar cells will open a new market for solar applications, and the market potential is huge, because the surface area of windows is much larger than that of roofs

although this perovskite material can only produce a small amount of electricity, the efficiency is only 0.5%, which is not enough to produce meaningful energy. However, it can trigger the reaction, so as to darken the glass, reduce the external heat entering the building, and reduce the load and use of the air conditioning system

The efficiency of

0.5% is far lower than that of crystalline silicon battery, especially the latter has reached 22% at present. But researchers believe that this is enough to provide power for darkening glass, thereby reducing the dependence on air conditioning

lunt said that his team can promote the efficiency of this material to about 4%, so that transparent photovoltaic (TPV) can provide energy for buildings

crystalline silicon technology is still difficult to replace at present, but transparent photovoltaic (TPV) can serve new markets. The world is urbanizing. Modern cities have a large number of glass windows and vertical surface areas that can take advantage of this new technology

in addition to office buildings and houses, lunt believes that this material can also be used as windows for cars, greenhouses and mobile electronic devices
