The solar battery has set a new record for efficiency – almost 50%

The new solar battery has set a record for efficiency. Researchers from the United States reported that it can convert light to electricity with an efficiency of 47.1%. Variation of the same cell set an efficiency record for intermittent lighting at 39.2%.

Scientists from the National Renewable Energy Laboratory (NREL) in the United States set a new world record for solar energy conversion efficiency. They did this thanks to an innovative element that converts light into electricity with an efficiency of almost 50%.

They used a “six-junction” element in which there are 140 layers of semiconductor materials to achieve a conversion factor of 47.1%. This is a new record – researchers exceeded the result of 46%, set by the Fraunhofer Institute in Germany.

When creating the device, NREL researchers relied on materials III-V; they have a wide range of light absorption properties. Each of the six compounds of the cell was specially selected to capture light from a certain part of the spectrum. For maximum efficiency, scientists have created 140 layers from a combination of different materials.

“This device demonstrates the extraordinary potential of multi-layer solar cells. In the near future we will achieve an efficiency of 50%, ”said John Geish, lead researcher and chief researcher at the NREL High-Efficiency Photoelectric Crystallography Group.
