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.
