Idemitsu developing CIGS solar modules for satellites
Japan’s oil giant Idemitsu Kosan and U.S.-based Source Energy Company announced a collaboration to develop copper indium gallium-selenide solar modules and arrays for satellite and space applications.
Ascent Solar testing CIGS modules for power beaming, marine applications
The US-based developer of copper indium gallium selenide thin-film PV products said its modules will be tested without modifications by companies developing marine PV and power beaming applications.
Improving solar windows via microfabrication techniques
Researchers in Europe are investigating semi-transparent solar windows, applying microfabrication technniques to both CIGS and perovskite devices, to overcome the view-impeding properties of earlier solar window concepts.
Ascent Solar unveils production scale 15.7% CIGS modules for space
US-based Ascent Solar Technologies says its latest 30cm2 Titan solar module has a power density of 1,960 W/kg and is designed for space applications.
Midsummer bags 15 MW CIGS production line order
Swedish thin film solar specialist Midsummer announced the order of a SEK 143.5 million ($14.8 million) turnkey line with a capacity for 15 MW from an undisclosed Swedish industrial and defense group.
Roltec plans CIGS solar module factory in Poland
Germany’s Singulus Technologies will provide three of its physical vapor deposition (PVD) vacuum sputtering systems to Poland-based module manufacturer Roltec at a new plant that will produce copper, indium, gallium, and selenium (CIGS) cells on glass substrates.
CIGS cell with ultra-thin glass substrate hits record efficiency of 17.81%
South Korean researchers have fabricated a copper indium gallium selenide (CIGS) solar cell with a 90 μm-thick UTG provided by South Korea’s Unique Technology Integral. The device uses a cadmium-free buffer layer made of zinc oxide and magnesium oxide, instead of cadmium sulfide.
Helmholtz-Zentrum Berlin hits 24.6% efficiency for perovskite-CIGS cell
Germany’s Helmholtz-Zentrum Berlin (HZB) has achieved a world-record 24.6% efficiency rating for a perovskite-copper indium gallium selenide (CIGS) tandem solar cell. Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has confirmed the result.
Chinese researchers build 4T perovskite-CIGS tandem solar cell with 29.36% efficiency
Scientists in China built a four-terminal perovskite-CIGS tandem solar cell based on a top semi-transparent perovskite device with an efficiency of 21.26% and a high bifaciality factor of 92.2%. They used a solvent-annealing strategy to produce a perovskite film with full coverage, larger grains, superior crystallinity and free of detectable lead iodide impurity.
