Scientists at the University of Brunswick in Germany have developed a new type of solar concentrator that concentrates light from any direction on a solar panel. The researchers said the funnel can be tuned to different wavelengths of light and stacked Together, the entire spectrum can be converted into electricity.
A solar concentrator is a type of lens that concentrates sunlight on a small area, and since most solar cells are only suitable for working in direct sunlight, they are not widely used in solar energy.
But the new concentrator consists of a randomly oriented pigment that absorbs light from almost any angle of incidence and maps it onto a component oriented in a single direction with a loss of only 10% It shows that this condenser can absorb about 99% of the incident light and the light redirecting quantum efficiency is more than 80%.
Scientists predict that in the future it is possible to stack concentrators of different amplitudes on top of each other to form a concentrator that absorbs the entire spectrum and because these concentrators are made of inexpensive and versatile materials, Developed as a cost-effective solar cell booster.
