After an interim high in 2021, polysilicon imports into China fell again in 2022, but the country’s share in global output still came close to 90%, according to a new report by Bernreuter Research.

Zigor has developed a modular central inverter that can convert AC power to DC power for battery charging. It has an output of 3.3 MVA and a DC voltage of up to 1,500 V.

Pumped hydro energy storage can be readily scaled to any required storage capacity at a known and affordable cost.

Solargiga is offering three versions of its new bifacial panels, with power outputs of 415 W to 425 W and efficiency ratings ranging from 21.25% to 21.76%. They feature 108 half-cut monocrystalline cells with n-type technology.

Worldwide Universities Network researchers used cheap and abundant starting materials to synthesize a small molecule organic electrode material and achieved a considerable performance boost with various battery chemistries. The new cathode material exhibited unparalleled cycling stability, ultra-high capacity, and rate capability in aqueous zinc-ion batteries.

BayWa re’s ECOwind subsidiary and Austrian energy supplier EVN have finished building a 24.5 MWp floating PV plant in Grafenwörth, Austria. They claim it is the biggest such installation in Central Europe.

Green hydrogen production capacity continued to grow last year, driven largely by new investments, GlobalData says in a newly published report. Deutsche Bahn, meanwhile, has revealed plans to expand its hydrogen bus fleet in Germany.

A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.

South Korean researchers have revealed a scalable production method for platinum-based fuel cell catalysts, while Germany moved forward on its hydrogen strategy by signing agreements with Australia, Belgium, and the Netherlands.

pv magazine speaks with Matthew Watson, president of Precious Metals Commodity Management LLC, about silver demand and availability. He says the solar industry has managed to reduce silver consumption, but it may have to do more in the future.
