Pyramid shaped age concentrator can bring three times the amount of light to solar panels

Research authors Nina Vaidya and Olav solgaard said in their peer-reviewed papers that this new technology called “axially graded index lens” (Agile for short) shows a way to improve the efficiency of static solar panels, and the same is true under diffuse light conditions.

In the laboratory, the prototype lens array has successfully concentrated light into a 1/3 small area, and can maintain 90% efficiency under the best condition.

Even when the incident angle of the light is more biased, this scheme is far better than the traditional basic concentrator (sometimes at the expense of light intensity / but focusing more on the applicable angle).

These concentrating schemes don’t sound new. After all, concentrators such as Fresnel lenses or planar mirrors only have moderate receiving angles. In contrast, the pyramid shaped concentrator rendered in the new article looks more charming.

It is reported that the research team has formulated a three-step plan. On the basis of the pyramid concentrator originally made of bonded glass, they have also created a version with aluminum side walls. If all goes well, this technology is expected to be directly put into use in the production line of photovoltaic panels.
