Cigs Solar Cell Efficiency Record

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.

Cigs solar cell efficiency record.

A small sample of the perovskite cigs tandem solar cell. The test cell is made of copper indium gallium diselenide cigs and has a surface area of 0 5 cm. 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 metal halide perovskite compounds mainly convert visible parts of the spectrum whereas cigs semiconductors deal with the infrared light. The world record cell combines the semiconductors perovskite and cigs to a. The tandem cell resulting from this collaboration achieves a record efficiency of 24 6 percent. John geisz left and ryan france researchers on the nrel study that broke the 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. 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. 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. 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.
