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.

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. 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 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 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 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. The thin film solar cell has an efficiency of 22.

The tandem cell resulting from this collaboration achieves a record efficiency of 24 6 percent. 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. 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.
