A new scientific paper takes a closer look at the record-breaking efficiency that Australia’s Sundrive announced for a silver-free heterojunction cell in September 2021, as certified by Germany’s Institute for Solar Energy Research.

A five-year Sandia Labs study on solar module degradation shows that 13 out of 23 tested module types have effective lifetimes exceeding 30 years.

NREL and Berkeley Lab have proposed efficiency and stability best practices for solar water-splitting to make hydrogen, while a team of researchers from Malaysia and Pakistan have revealed their findings on the feasibility of hydrogen-based incineration.

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.

The worst effects of the pandemic may have passed, but supply chain disruptions continue to be felt across the world. The effects of the war in Ukraine are also evident to all of us in our daily lives, from commodities to energy, food supply chains and beyond. The disruption in the battery energy storage system (BESS) supply chain is no different, writes Cormac O’Laoire, senior manager of market intelligence at Clean Energy Associates. Indeed, as the cost of raw materials such as lithium climb, battery prices are being driven materially higher, on some accounts by 20% to 30%, rendering some projects uneconomical.

While not one of the big five-year-cycle COPs like Paris or Glasgow, COP27 is still hugely important, write Wood Mackenzie analysts. The fallout from the conflict in Ukraine has tilted the precarious balance of the energy trilemma – sustainability; affordability; security – towards the latter. But despite this temporary setback, some progress should still be possible.

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.

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 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.

The US National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritised over closed-loop recycling to reduce demand for new materials.
