Panasonic claims 16.09% efficiency for lightweight perovskite solar module

The device has an area of 802cm² and thickness of 2mm. The manufacturer claims it improved module performance through an inkjet coating method and a reduction in weight by using thin glass substrates.

Mysterious new chlorophyll with potential PV applications

Japanese researchers are studying the ‘Chl f’ substance which features a pigment in photosynthesis which can absorb far-red light from the lower end of the spectrum.

Half-cut modules from Sharp

The Japanese electronics giant has unveiled three monocrystalline half-cut cell modules said to provide 2-3% better performance than standard, full cell panels. The claimed efficiency of the modules exceeds 19.5% and Sharp says power output ranges from 330-395 W.

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.
