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.
Cadmium-free CIGS solar cell with 18% efficiency
South Korean scientists manufactured the cell with the chemical bath deposition method, using different thiourea concentrations. For the buffer layer, they used zinc instead of cadmium sulfide. The cell is flexible and is available in seven different colors.
Japanese manufacturer acquires rights to produce 23.26% efficient CIGS perovskite cell developed by HZB and Kaunas University
The research group that developed the cell said the two materials used to produce it, dubbed 2PACz and MeO-2PACz, will soon be commercially available. The material consists of 1-2nm of self-assembled monolayers deposited on the surface of the perovskite by dipping it into a diluted solution.
