Scientists in the United States have used microwaves to convert ubiquitous plastic packaging material polyethylene terephthalate into a battery electrode component. The researchers say anodes based on the material could be suitable for both lithium-ion and sodium-ion devices.

A rebranded Singyes Solar was able to stave off a debt default meltdown last year thanks to a $200 million cash injection from the state but the turnaround appears to have come at a hefty cost in longer-term borrowings and employees.

The Nordic nation is now the third European country to have waved goodbye to coal for power generation. Another 11 European states have made plans to follow suit over the next decade.

A U.K. study has identified 13 soiling agents with differing effects on light transmittance. Researchers found some dust particles were able to degrade photovoltaic performance by as much as 98%.

Solaria says that it will start selling its new all-black panel for residential PV applications in the U.S. market within the current quarter. The monocrystalline module is equipped with a microinverter from Enphase and has an efficiency rating of 20.2%.

Solar capacity is expected to grow to unthinkable levels in the tiny country, according to a new report by Netbeheer Nederland. Under one scenario in which regional governments and companies would take the lead in the energy transition, cumulative solar capacity could reach 125 GW. Under a second scenario, in which growth would be driven by the central government, total PV capacity could hit 106 GW.

Indian scientists have developed a low-cost electrocatalyst based on iron, manganese and N-doped carbon derived from fish gills (Fe/Mn/N-FGC) to increase the performance of a homemade rechargeable zinc-air battery. The Fe/Mn/N-FGC cathode-based battery achieved open-circuit voltage of 1.41 V and a large power density of 220 mW/cm2 at 260 mA/cm2 current density – compared to 1.40 V and 158 mW/cm2 for a commercial platinum/carbon-based battery – with almost stable charge-discharge voltage plateaus at high current density.

The solar efficiency leader remains on track to complete its planned split into two independently focused pure-play solar companies by the end of the second quarter.

EuPD Research estimates around 65,000 energy storage systems linked to rooftop PV were installed last year thanks to increasingly popular solar arrays and electric vehicles as well as rising electricity prices.

Portuguese electric utility EDP will supply power to Dutch nutrition, health and sustainable lifestyle multinational Royal DSM. The agreement relates to 59 MW of solar and wind generation capacity.
