Japanese scientists have created a protective film that reduces the reflective properties of the solar cells used in solar power plants.
Moth eyes are not only able to see in the dark, but also have "anti-reflective" coating which protects the insect from predators preying on him. This feature experts from the University of Tokyo Metropolitan tried to use for the benefit of alternative energy.
Because of the design features of solar panels reflect some of the light, thus greatly reducing the amount of energy produced. This helps to reduce the effect of a special film with nano, which is similar in structure of the eye moth.
Tests conducted in the laboratory and in the field (as Tokyo is not very sunny region, the second site was the capital of the U.S. state of Arizona Phoenix) have shown that the efficiency of solar cells increased by 5-6%. The numbers may seem small, but in absolute terms, gives a very tangible benefit.
The greatest difficulty is the development of a mechanism for producing the film, and then the researchers came to the aid of engineers from the chemical company Mitsubishi Rayon. Now, the whole team is busy increasing product life and its adaptation to different types of devices, accumulating solar energy, and in the future — under the window glass and computer screens.
Work process and its results were published in Energy Express, Supplement to Optics Express.
