Pure sulfide CIGS solar cell with 15.2% efficiency
The device was built by an international research team. The cell features a buffer layer based on zinc sulfide oxide and a low copper absorber. The cell showed an open-circuit voltage of 920 mV. And though a different material from the widely commercialized CIG selenide PV thin films, the researchers claim similar processes could be used in its large-scale manufacturing.
Avancis claims 19.64% efficiency for CIGS module
The German manufacturer said the result was confirmed by the US National Renewable Energy Laboratory. The achieved efficiency is claimed to be a world record for a CIGS panel with an integrated series connection of 30×30 cm.
Solliance, MiaSolé hit 26.5% efficiency on tandem CIGS/perovskite solar cell
MiaSolé and Solliance have achieved record performance by optimizing the bandgap and the efficiency of both the rigid semi-transparent perovskite top cell and the flexible CIGS bottom cell.
Midsummer ships CIGS production line to Russia
The production equipment was bought by Russian nanotechnology specialist Rusnano. The line will be used to produce BIPV modules at a factory in the Republic of Mordovia.
Nice Solar Energy files for insolvency under self-administration
The CIGS thin-film specialist employs 160 people in Germany. Business operations will continue with no disruption for the time being.
Vanadium redox flow battery integrating CIGS modules
Spanish and Finnish scientists have developed a solar vanadium redox flow battery paired with commercially available CIGS solar panels. The open-circuit voltage values were high enough to achieve unbiased photocharge, they said.
Midsummer to set up 50 MW BIPV module factory in southern Italy
Through this new project, the Swedish CIGS turnkey equipment supplier aims to expand its presence in southern European PV markets.
