Record of solar power efficiency

Scientists at the US Department of Energy have successfully developed solar cells that convert 44% of light into electricity.

However, to achieve such efficiency, it is necessary to increase the energy of the sun by nearly 1,000 times, according to NBC News.

The research is still underway at the National Renewable Energy Laboratory of America, where the previous record was set at 43.5 percent.

Researchers have achieved record-breaking performance after cramming multiple junctions into a solar cell, each of which absorbs light at different wavelengths.

In the process, they accidentally discovered a new material, but it was hard to produce in real life.

In the tested system, the energy is measured by the 'sun': a beam of light 10 times that of the sun is simply described as 10 suns.

To achieve a record-breaking performance of 43.5%, experts must use the system to create 415 "suns."

And with the latest record, experts need 947 suns to make it.
