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.
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.
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.
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.
