Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

Last month, in a pv magazine Webinar held in partnership with Endurans Solar, we took a closer at Endurans’ conductive backsheet for back contact modules, and examined recent progress in back contact cell and module technologies, and their growing market potential over the next few years. Here, presenters Hugo Schoot, Business director at Endurans Solar, and Bram Verschoor, CCO at equipment supplier Eurotron, answer a more of the questions posed by the audience during the webinar.

Austrian researchers have demonstrated a chemical looping system can be retrofitted into biogas plants. It is said the new tech can produce high-purity hydrogen for fuel cells on an industrial scale. The scientists concerned said their system could produce hydrogen, on a decentralized basis, for €5/kg.

Scientists in Germany investigated various routes to optimizing cell design for perovskite-silicon tandem products. Beyond the perovskite layer itself, they note several other areas that should be optimized for tandem cells, taking silicon heterojunction processing as a starting point. The research identifies several routes to cut costs in cell production, including a significant reduction in indium consumption.

Through the inventory, an international group of researchers was able to identify 68,661 PV facilities, totaling 423 GW across 31 countries. According to the scientists, the online database provides insight into global trends for PV siting decisions, as well as into the gap between facility-level final investment decisions, construction start dates, construction completion dates and facility operations.

The past 12 months have proved profitable for polysilicon manufacturers, as selling prices have soared to levels not seen since 2011. However, with major new capacity expansions on the horizon from most of the leading manufacturers, and new players planning to enter the scene, the market balance looks set to shift. Exawatt’s Alex Barrows rounds up where the industry stands and what might happen next.

UK research firm Wood Mackenzie reports that Northeast Asia and Europe are expected to become the main hydrogen importers, accounting for 55% of seaborne hydrogen trade, whereas Australia, the Middle East and, possibly, Russia and the U.S. have the greatest export potential. Plug Power and Lhyfe closed a deal to build green hydrogen generation plants throughout Europe.

The latest edition of a clean power jobs survey produced by IRENA and the International Labour Organization has stressed the important role which will need to be played by the public sector if the energy transition’s employment benefits are to be shared equally.

The input costs of the two biggest contributors to solar plant development expense have gone through the roof since the world began to come out of Covid-19 lockdowns, to leave project developers with some difficult choices.

Elsewhere, Snam and Toyota are pushing for more hydrogen-based mobility in Italy, and Woodside Petroleum wants to establish an export-oriented hydrogen and ammonia production facility in Australia.
