Cigs Solar Cell Efficiency Record

The metal halide perovskite compounds mainly convert visible parts of the spectrum whereas cigs semiconductors deal with the infrared light.

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. 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. 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.
