Indium supply not an issue for CIGS industry
Scientists Ayodhya Tiwari and Daniel Lincot recently spoke to pv magazine about the future of copper indium gallium selenide solar tech, which could play a key role in providing flexible, lightweight products in the building-integrated PV segment.
Semitransparent bifacial CIGS cell with 10.5% efficiency
The solar cell was developed by Korean scientists for power-generating window applications. They built the device with transparent conducting oxide (TCO) rear contacts and a textured polydimethylsiloxane (PDMS) layer with light-scattering and antireflection properties.
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.
Can CIGS thin-film PV manufacturing return in the US?
A scientist familiar with First Solar’s earlier efforts in CIGS makes the case for the CdTe pioneer to return to the technology.
CIGS cells could hit efficiencies of 33%, say Germany scientists
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.
CIGS cells for micro-concentrator PV devices
Scientists have developed a new micro CIGS cell by using an area-selective electro-deposition process as a material-saving technique. It has a conversion efficiency rate of 5.2% and a high open-circuit voltage.
