A new solar cell technology has broken the old 22% efficiency record, all of that with a 6-junction solar cell design, something that was thought unachievable for the past decade.
Developments in production methods of the famous III-V group of Semiconductor elements (IUPAC 13-15), was able to arrange them in unique ways to generate this amazing technology, all thanks to their distinctive alloy properties.
Groups III-V of the periodic table are known for their special characteristics that, when combined, produce a wide range of energy bandgaps that can be used in multitude of different electronics devices.
The most commonly known combination is Indium Gallium Arsenic or InGaAs …Fart noise… which is widely used in solar panels. In this new research they explored other elements of the group with a variety of combinations which ultimately increased solar panels conversion efficiency to a whopping 39.2% efficiency at one-Sun.
