Cigs Solar Cell Efficiency Record

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.

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. John geisz left and ryan france researchers on the nrel study that broke the solar cell efficiency record. The tandem cell resulting from this collaboration achieves a record efficiency of 24 6 percent. 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.

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 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 thin film solar cell has an efficiency of 22. The test cell is made of copper indium gallium diselenide cigs and has a surface area of 0 5 cm.

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 metal halide perovskite compounds mainly convert visible parts of the spectrum whereas cigs semiconductors deal with the infrared light. 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. A small sample of the perovskite cigs tandem solar cell.

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