Cigs Solar Cell Efficiency Record

Independently verified record efficiency up to 22 9 measured by national institute of advanced industrial science and technology aist for cigs solar cells has been achieved on a 1 cm2 device.

Cigs solar cell efficiency record.

The test cell is made of copper indium gallium diselenide cigs and has a surface area of 0 5 cm. The record efficiencies for thin film cigs cells are slightly lower than that of cigs for lab scale top performance cells. A small sample of the perovskite cigs tandem solar cell. In 2008 cigs efficiency was by far the highest compared with those achieved by other thin film technologies such as cadmium telluride photovoltaics cdte or amorphous silicon a si.

The perovskite top cell in the tandem uses light in the visible part of the solar spectrum while the light in the near ir spectrum that passes through the perovskite cell is harvested by the underlying cigs cell. The world record cell combines the semiconductors perovskite and cigs to a. A special branch in the famous nrel chart for solar cell world records refers to a newly developed tandem solar cell. Solar frontier has set a new record for thin film solar cell efficiency at 23 35 representing a 0 4 improvement on its own record of 22 9 set in late 2017 the results have been.

Scientists at helmholtz zentrum berlin have developed tandem cells that combine two different semiconductors and convert different parts of the light spectrum into electrical energy the new perovskite cigs tandem cell achieves a record efficiency of 24 16. The metal halide perovskite compounds mainly convert visible parts of the spectrum whereas cigs semiconductors deal with the infrared light. The tandem cell resulting from this collaboration achieves a record efficiency of 24 6 percent. The cigs cell was made on a commercially available high efficiency flexible solar cell technology fabricated on ultra thin stainless steel foil using miasolé s proprietary high throughput roll to.

The claimed conversion efficiency improves on the 24 6 the researchers announced in september 2018 for a perovskite based tandem cigs solar cell the imec press office told pv magazine.
