Technology and R&D

Heat pumps are increasingly used for domestic hot water in Europe due to their efficiency and compatibility with solar power, but their lower operating temperatures can create conditions where Legionella pneumophila may grow if systems are poorly designed. Proper hydraulic design, temperature control, and periodic thermal disinfection ensure both high efficiency and safe, hygienic operation.

Toshiba has unveiled a PV management platform within its Spinex for Energy portfolio that enables real-time monitoring and O&M of multiple solar plants.
The system uses AI to track plant performance, detect faults, calculate capacity and PR metrics, automate reporting, and support troubleshooting.

Researchers at Germany’s Fraunhofer FKIE institute developed PowerRange, a virtual simulation platform that helps power grid operators safely test cybersecurity measures and respond to realistic cyberattacks. The platform supports both traditional and renewable grids, offering immersive training across IT, OT, and control systems while highlighting the importance of coordination, communication, and practical defense strategies.

Nearly 20 years after the first perovskite solar cell was developed, its efficiency and durability are drawing interest from industries worldwide. The defense sector is among the most active, as rising geopolitical tensions drive record government spending to protect critical systems from disruption and attack.

Researchers from Australian National University and Longi used photoluminescence imaging to analyze dopant distributions in RCz-grown silicon wafers doped with antimony, phosphorus, and gallium, finding highly uniform radial concentration profiles suitable for high-efficiency solar cells. The study also found that antimony-doped wafers provide more stable axial doping along the ingot, highlighting their potential for next-generation photovoltaic manufacturing.

The Chinese manufacturer said its new back-contact module delivers up to 545 W and over 25% efficiency in a compact rooftop format for residential, C&I, and off-grid applications.

German manufacturer Ehret has launched SolarSlide, a sliding shutter with integrated PV modules developed with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). It provides solar shading while generating electricity for residential and commercial facades.

The Danish company says its new product is ideal for small to medium-sized solar cell testing. It can simulate light conditions in the 390–700 nm range.

In its second monthly column for pv magazine, the Becquerel Institute explains that Europe has vast commercial and industrial rooftops suitable for solar, but decades-old structural limits block conventional PV panels, creating an 85 GW untapped potential. Lightweight PV modules, commercially available and up to 50% lighter, can unlock this constrained market, meeting regulatory, economic, and technical needs for solar deployment across the continent.

Researchers have developed a PFAS-free dual-layer sol-gel and hydrophobic silica coating that repels water, dust, and dirt while maintaining high light transmission for solar panels. The transparent, self-cleaning coating improved photovoltaic efficiency from 13.90% to 14.56%, demonstrating strong durability and potential for future commercial applications.
