Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active power–frequency relationship, the novel technique optimizes the use of available headroom, reduces frequency deviations, and enhances overall grid resilience.

The Italian manufacturer said that its new monobloc propane heat pump can produce hot water at temperatures of up to 70 C, with a coefficient of performance of up to 5.31.

BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory.

The price of silver rose above $44 per ounce this week after gaining more than 30% in six months, with silver expert Philip Newman telling pv magazine it could exceed $50 per ounce next year, raising pressure on PV module makers to curb silver use.

A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.

A 12-month testing of a 1.1 MW pilot PV facility built in 2016 in Algeria’s desert has shown that tracking-equipped ground-mounted PV can reach high performance ratio values under Saharan conditions. The plant was built with a variety of PV module technologies.

New research from the Netherlands showed that renewables and short-term storage can meet around 92.5% of Europe’s electricity demand in future energy scenarios, with the remaining 7.5% being satisfied by green hydrogen. The scientists considered Europe as fully self-sufficient with zero import-export of power or hydrogen, with each of the 37 countries included in the modeling having a self-sufficiency rate of at least 80%.

Researchers in Germany have shown that heterojunction solar cells screen printed with silver-copper on the front side and silver paste on the rear side can achieve a 0.13% efficiency gain over reference screen-printed bifacial cells based on silver alone. The research group worked specifically on dispensing and screen printing as printing methods.

Sarawak Energy says it will grant rebates of up to $2,800 for PV systems planned to operate under Malaysia’s net metering scheme.

The cell was fabricated with a 2.3 nm-thin layer of gallium oxide, a silver busbar aimed at improving charge collection and silicon nitride anti-reflection coating. It was encapsulated within a watertight 3D-printed box to ensure impermeability.
