The real cybersecurity debate around chinese inverters is only just beginning
The European Commission’s move to restrict funding for projects using high-risk inverter vendors marks a turning point for solar cybersecurity. In this article, Uri Sadot, founder of SolarDefend and a longtime renewable energy cybersecurity specialist, explains why banning Chinese inverters may support Europe’s strategic independence, but will not solve the sector’s cybersecurity challenge. The road to greater security must include clear technical standards, stronger asset visibility and practical implementation of NIS2.

Hot weather and clear skies give Europe a bumper May
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Europe’s May weather was marked by a mid-month Arctic cold outbreak followed by a persistent heat dome that brought clear skies, record temperatures, and above-average solar irradiance across much of Central and Western Europe. While the blocking high boosted irradiance by up to 25% in some regions, cloudier conditions on its fringes left areas such as Scotland, Ireland, and Norway with below-average solar resource.

Perovskite tandem PV for agrivoltaics
Researchers evaluated “farm-to-fork” life-cycle impacts of agrivoltaic lettuce systems using perovskite–silicon and perovskite–perovskite tandem PV, comparing them with conventional silicon PV across major US growing regions. The study finds that integrating advanced tandem solar with farming can reduce irrigation demand and significantly cut greenhouse gas emissions—potentially offsetting up to 30.9 million tons of CO₂ and saving around 8.4 billion m³ of water annually under favorable conditions.

Scientists build PEDOT:PSS-free all-perovskite tandem solar cell with 29.1% efficiency
PEDOT:PSS is commonly used as a hole transport layer in perovskite solar cells because it combines high transparency, good conductivity, and suitable energy-level alignment, but its moisture sensitivity and acidity can damage perovskite layers and limit long-term stability. In contrast, replacing it with a phenothiazine-based self-assembled monolayer allows better interfacial control during crystallization, lowers defect densities, and enables highly efficient all-perovskite tandem devices with a reported efficiency of 29.1%.
