Infrared Solar Panel Efficiency

Infrared solar cells will boost solar power by up to 25 and eventually double brian wang november 2 2019 a research team led by hans ågren professor in theoretical chemistry at kth royal institute of technology has developed a film that can be applied on top of ordinary solar cells which would enable them to use infrared light in energy conversion and increase efficiency by 10 percent or more.

Infrared solar panel efficiency.

Due to the many recent advances in solar cell technology over the last 5 years average panel conversion efficiency has increased from 15 to 20. Visible light accounts for under half of the solar energy that reaches earth s surface. Solar panels mostly convert visible light into electrical energy and they also can make use of almost half the infrared energy. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity.

Infrared heating panels use less energy than traditional convection heaters because they heat the surface of a room rather than the volume. To prevent this a transparent silica crystal layer can be applied to solar panels. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. In the past year alone there have been milestones in solar efficiency solar energy storage wearable solar tech and solar design tech.

That might sound low but scientists believe that with current technology solar panels will hit a peak. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Another savings benefit of infrared heating panels is that they can be utilised to provide a home with a fully zoned system. Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity.

But solar panels only use a small portion of ultraviolet. 6 minutes solar power is in a constant state of innovation in 2019 with new advances in solar panel technology announced constantly. Applied as a thin film over the top of a regular solar cell this has the effect of spatially modulating the infrared light concentrating it in just the right way to greatly improve the efficiency. An increase in solar cell temperature of approximately 1 c causes an efficiency decrease of about 0 45.

The silica layer acts as a thermal black body which emits heat as infrared radiation into space cooling the cell up to 13 c. Nearly all of the rest comes from infrared radiation. Sunlight energy that reaches the ground is around 4 ultraviolet 43 visible light and 53 infrared. Solar cell efficiencies could increase by 30 percent or more with new hybrid materials that make use of the infrared portion of the solar spectrum researchers say.
