Cigs Solar Cell Efficiency Record

A special branch in the famous nrel chart for solar cell world records refers to a newly developed tandem solar cell.

Cigs solar cell efficiency record.

The world record cell combines the semiconductors perovskite and cigs to a. The metal halide perovskite compounds mainly convert visible parts of the spectrum whereas cigs semiconductors deal with the infrared light. 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 tandem cell resulting from this collaboration achieves a record efficiency of 24 6 percent.

A small sample of the perovskite cigs tandem solar cell. John geisz left and ryan france researchers on the nrel study that broke the 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 centre for solar energy and hydrogen research baden württemberg zsw created a new cigs cell in their lab which sets a new european efficiency record.

The record efficiencies for thin film cigs cells are slightly lower than that of cigs for lab scale top performance cells. 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. 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 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.

The thin film solar cell has an efficiency of 22.
