Some northern states added as much small-scale PV per capita as the top states in the Southwest, taking advantage of solar irradiance in northern states that’s about 70% as high as that in the desert Southwest.

With senators having called for plantation-wide solar powered pumping projects, funded by public money, the country’s National Irrigation Administration has agreed and said it wants to embrace floating solar facilities too.

A consortium of developers led by ACWA Power has secured financing for the Red Sea project, on the west coast of Saudi Arabia, which is set to feature a 320MW solar array and a 1.3GWh off-grid battery.

The project is planned to be located 35km from Bucharest, in central Romania. The plant will be close to grid infrastructure and is expected to occupy a surface of 150 hectares.

The device integrates various current outlets that enable it to recharge, simultaneously, mobile phones, tablets or computers as well as all kinds of low-consumption electronic devices such as small appliances or electric tools, by simply unfolding the solar panels and connecting them.

The new numbers show France deployed around 100MW more solar power than previously estimated by French renewable energy association the SER.

In a short interview with pv magazine, Flemming Vejby Kristensen, from the Danish PV association Solcelleforening, explained the surprising performance achieved by Denmark’s PV market in 2021, in which around 667.6MW of PV capacity was deployed. Around 94% of this growth is coming from large scale unsubsidized solar projects and the segment’s main driver has been the willingness of big corporations to buy green electricity under bilateral PPAs.

Swedish researchers have developed a novel way to manufacture micro supercapacitors, also known as system-on-a-chip, so they are compatible with other components in system circuits and can be easily tailored for different uses.

The realization of biodegradable batteries is a step closer thanks to research from South Australia’s Flinders University, which has developed a 2.8V organic polymer battery. While this battery was made from synthetic polymers, research lead Zhongfan Jia told pv magazine Australia the team’s future iterations will source “materials directly from nature” saying this promises to reduce waste and reliance on mined materials and could have novel applications in fields like biotech.

Built by a Dutch-Chinese research team, the cell is relying on a new type of hybrid-shaped Cu finger consisting of a rectangular bottom part and a round top part, which was integrated into the cell through a 2-step electrochemical deposition process. The Cu-plated device outperformed both optically and electrically a reference cell fabricated via screen printing.
