Dutch scientists have achieved a record-breaking efficiency for a silicon heterojunction solar cell fabricated with a hole collector based on a molybdenum oxide (MoOx). They used plasma treatments to increase the presence of oxygen in the MoOx layer, to improve its electronic properties.

Australia’s two main tracker companies, Nextracker and Array Technologies, are launching terrain-following products to mitigate and even eliminate the need for earthworks on site, opening up previously unsuitable land for solar.

Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.

State Power Investment Corp. (SPIC) has started operating the world’s first offshore floating solar plant integrated with an offshore wind turbine, at a pilot site off the coast of China’s Shandong province. It features floating PV tech from Norway’s Ocean Sun.

Solinteg is offering five versions of its new three-phase hybrid inverters, with nominal power ranging from 25 kW to 50 kW, an efficiency rating of 98.8%, a European efficiency of 98.3%, and up to 4 MPPTs.

Researchers in Singapore have developed a new light-triggered coupled oxygen evolution mechanism that builds on past oxygen evolution research. Oman, meanwhile, has announced a new hydrogen strategy.

An Israeli scientist has proposed a way to achieve uninterrupted PV power on the moon without using energy storage. The proposal involves the installation of PV panels around a 360-degree latitudinal ring close to one of the moon’s poles. There would be no inter-array shading, and static vertical PV arrays and arrays mounted on single-axis vertical trackers could be viable mounting structures.

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

Aspen Creek Digital, a US bitcoin miner, has started operations at a 30 MW bitcoin data center powered by an 87 MW solar park in Texas. The project is the company’s second solar-powered bitcoin-mining center.

US scientists recently put different bifacial solar cells and modules through a series of tests at elevated temperature, humidity, voltage and mechanical stress levels. The tests revealed a range of light-induced and potential-induced degradation mechanisms that modules will likely suffer in the field.
