Qatar’s 800 MW tender draws world record solar power price of $0.01567/kWh

The winning consortium was formed by French oil giant Total and Japanese conglomerate Marubeni Corp.

All-inorganic perovskite solar cell hits 16.1% efficiency

Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.

Panasonic claims 16% 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.

China will extend duties on US and South Korean polysilicon for another five years

The Chinese government will extend duties on U.S. and South Korean polysilicon for another five years despite committing to buy $200 billion more U.S. goods and services over the next two years in return for America halving 15% tariffs applied to $120 billion worth of Chinese products.

World record efficiency for Longi’s PERC mono, Jinko’s p-type PERC and bifacial solar panels

Solar module efficiency records continue to fall. Longi claims a 22.38% efficiency world record for a PERC mono panel, while Jinko has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively.

Solar modules from Sharp with half-cut technology exceed 19.5% efficiency

The Japanese electronics giant has unveiled three monocrystalline half-cut cell modules said to provide 2% to 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 W to 395 W.

US scientists claim clear-sky irradiance model provides better results for module testing

Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.

Huawei faces three more Solaredge lawsuits

Inverter manufacturer Solaredge has filed three additional patent infringement lawsuits against its competitor, Huawei, in China. This comes after three similar legal actions against Huawei that had been undertaken by Solaredge in Germany last summer. While Huawei has decided not to comment on the matter, the Chinese manufacturer revealed that it had filed three patent litigation claims against Solaredge at a Chinese court this May.

The slow, inexorable rise of green hydrogen

The International Renewable Energy Association says the integration of hydrogen into the energy transition will not happen overnight and electrolysis costs will not be halved until the 2040s. But that hydrogen and related products could revolutionize the world energy landscape is not in doubt.

Logic supports renewables, not nuclear

The latest edition of the World Nuclear Industry Status Report reiterates that clean power is taking the lead in the world’s energy system and nuclear is not only too costly a remedy for carbon emissions but too slow to deploy.
