Technology and R&D

New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.

Conceived by researchers from Iran, the new conductive adhesive ink is made of polymethyl methacrylate (PMMA) and is used as an interlayer between the cell’s hole transport layer and carbon foil. It reportedly ensures higher cell stability while also providing remarkable efficiency.

Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling. The proposed system has so far provided low exergy levels, but its costs are much lower than those of conventional vapor compression refrigeration technologies.

Indian manufacturer VSole has introduced single-phase hybrid inverters 3 kW to 6 kW with power output ratings. The inverters reportedly allow uninterrupted power to the connected loads, with a UPS-level switching time of four milliseconds.

The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.

University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of US cities under moderate climate change, and by up to 20% by the end of the century.

An international team of researchers has proposed a series of processes to recover silicon and other metals from recycled solar cells. Their goal is to reuse the recovered silicon in the PV supply chain.

Australian researchers have developed multi-stage algorithms to remotely detect and accurately diagnose underperforming solar panels in residential and commercial PV systems.

British Gas has developed the Carbon Cruncher tool for the UK market. It contextualizes emissions by comparing them to other emitters.

Scientist in Canada have proposed to combine rooftop PV power generation with an alkaline electrolyzer and a fuel cell to generate hydrogen in buildings. The new system is intended at enabling seasonal energy storage and reduce a home’s levelized cost of energy.
