South Korean researchers have developed a long-term solar irradiance prediction method based on a reinforcement learning algorithm. They claim that the new model is able to forecast solar radiation for more than a year using just two weeks of solar radiation learning.

With utility scale solar installations accelerating, Philip Wolfe, founder of PV data consultancy Wiki-Solar, drills into the data to highlight some interesting variations in relative progress around the world.

Mattiq says it is evaluating “millions of combinations” of different alternatives to iridium for PEM electrolysis, while Hystar, Air Liquide, and Trillium Energy Solutions have revealed plans for the North American hydrogen market.

According to recently published employment report by the International Renewable Energy Agency (IRENA), the global solar industry employed around 5 million people at the end of last year. The report also reveals that women’s employment in the industry was “uneven”, with females mostly hired for administrative positions (58%) followed by science, technology, engineering, and mathematics (38%) and non-STEM technical positions (35%).

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Oxford Institute for Energy Studies researchers have developed a cost-effective material to absorb hydrogen at non-cryogenic temperatures, which they consider optimal for fuel cell storage systems.

Should the industry be alarmed at the potential degradation susceptibility of tunnel oxide passivated contact (TOPCon) solar cells? Or are the problems easily addressed and more a reflection of rushed-to-market products? pv magazine contributor and consultant Götz Fischbeck reports.

Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallisation and module interconnection.

As the energy storage trend unfolds, stories litter the media landscape about lithium-ion batteries catching fire, and even exploding. It’s a valid concern, and the time for consumers to understand a basic truth about lithium-ion batteries is long past due.

Australia’s solar market and pricing has been shaken up in recent months with the entrance of Tongwei Solar. Compounding this is the global free fall in panel pricing, which solar analyst Warwick Johnston says is yet to properly hit Australia. “There’s super cheap panels that are coming through and everyone will have to adjust their prices accordingly,” he says.
