The temperature of solar cells must be maintained relatively low, for efficiency and durability. However, active cooling systems, such as ventilation, are not practical. They are not only expensive, but they can also deflect and obstruct the light rays that are supposed to produce electrical power. To solve this problem, researchers at Stanford University have developed new type of solar cells that can be cooled automatically and thus are more efficient and durable.
The principle of this innovation lies in the shape of solar cells which are placed on the panels. In the form of small pyramids, they can deflect infrared waves that are heat carriers, while capturing visible light, which produces more electrical energy. Ultimately, these new optimized panels capture more energy, and their life is not shortened by heat. In the opinion of the scientists, this new generation of panels near perfection.
Research by the Stanford team are still far from complete, automatic cooling has yet to be tested in outdoor conditions. However, the researchers are expecting the early commercialization of this technology. Do not be surprised if ever you install a solar panel that produces more energy, and needs not to be replaced after a few hot summers.
It’s good to see that solar panels are growing and becoming more efficient. Eventually, they will take a larger share of renewable energy generation to preserve our planet Earth. In writing, we are concerned about the earth’s environment and therefore we welcome this discovery with enthusiasm. As for you, do you think it’s time to adopt the green energy on a more global scale?
