Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.

Scientists in Europe have put together a comprehensive guide to PV module degradation, examining literature and case studies on the topic as far back as the 1990s. Their paper details the primary stress factors faced by modules in the field, the most common modes of degradation and failure, and provides clear definitions relevant to reliability, quality and testing standards. Among their key findings is that a full understanding of how combinations of different stresses over varying timeframes is still missing from methods to estimate and improve system reliability.

Scientists in Belgium are exploring the potential of recycled silicon in solar modules at the end of their life cycle for reuse in low-cost, higher-energy-density storage technologies. They claim EV batteries using this silicon may allow faster recharging and travel longer distances on a single charge.

SolarEdge’s new bidirectional DC-coupled electric-vehicle (EV) charger enables vehicle-to-home and vehicle-to-grid applications and can seamlessly integrate with its home energy systems. It is scheduled for release in the second half of 2024.

First Solar has announced a limited production run of the “world’s first” bifacial solar panel with a cadmium telluride (CdTe) semiconductor. The pre-commercial Series 6 Plus Bifacial module is making its debut this week at Intersolar Europe in Munich, Germany.

Samsung and SMA are using a new cloud-to-cloud system that allows PV systems with SMA inverters to be integrated with Samsung heat pumps.

Recharge Industries, which had hoped to begin construction on its Geelong lithium-ion gigafactory this year, is reportedly refocusing its manpower on British endeavours. Despite Australia’s growing rhetoric around capturing more of the battery value chain, companies in the space are turning attention overseas.

UK scientists have developed Solar2Water, a system that generates twice the amount of water as conventional atmospheric water generators. The system operates efficiently with the same energy input, regardless of air humidity, relying solely on photovoltaics.

A Dutch research group has used a series of techniques from the automotive industry to develop a novel methodology to repair glass in double-glass solar panels. Their experimental work represents the step towards transforming glass-damaged solar panels from waste into valuable products.

A new study by the University of Hohenheim shows that shading from PV systems can improve agricultural yields, especially in dry periods, but additional research is needed.
