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.
The CIGS thin-film specialist employs 160 people in Germany. Business operations will continue with no disruption for the time being.
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.
Through this new project, the Swedish CIGS turnkey equipment supplier aims to expand its presence in southern European PV markets.
If you’re interested in some lightly used MOCVD and PVD thin-film solar cell production equipment, have we got a deal for you.
A scientist familiar with First Solar’s earlier efforts in CIGS makes the case for the CdTe pioneer to return to the technology.
Researchers have gradually improved the efficiency of CIGS thin-film tech in recent years. But scientists in Germany say the 23% rate achieved thus far is not the end of the story.
Scientists in the United States theorize that a ‘double absorber’ cell comprising two active thin-film layers within one cell stack could achieve impressive efficiencies, whilst eliminating many of the challenges inherent to the design of tandem cells. For now though, it’s only on paper.
