Zinc oxide UV shield cuts heterojunction solar cell degradation and boosts lifetime output by 4.8% Researchers in China have demonstrated that zinc oxide (ZnO) thin films can act as a ‘sunscreen’ for heterojunction solar cells, reducing UV-induced degradation while maintaining high visible-light transmission. ZnO-coated modules achieved lower projected LCOE and 4.8% higher cumulative power generation over 25 years.

Researchers warn of unexpected copper corrosion in perovskite solar cells Researchers in China found that copper electrodes in perovskite solar cells can suffer from edge corrosion during operation, reducing device performance. The team showed that adding a thin bismuth layer helps protect the copper electrode, limiting degradation and improving the long-term stability of the solar cells.

Agrivoltaics improve grape quality in Mediterranean rainfed vineyards Researchers in Italy found that agrivoltaic shading in Primitivo vineyards can reduce heat and water stress while improving vine physiology, growth, biodiversity, and yield under Mediterranean conditions. The study shows that photovoltaic integration can enhance vineyard resilience and maintain grape quality, although further long-term and multi-site research is needed to confirm its wider applicability.

Study shows consequences of PV-related fires are generally limited in severity An international study analyzed PV-related fires across the UK, Italy, Slovenia, and Sweden, showing that differences in reported fire rates are largely driven by national data collection methods and definitions. The researchers found that PV fires remain relatively rare, with data revealing that DC cables and connectors are the most common ignition sources.

New disaggregation methodology quantifies uncertainty in behind-the-meter PV generation Researchers in Spain have developed a conditional diffusion-based model to improve the visibility of behind-the-meter PV systems using low-resolution smart meter data. The probabilistic approach enables accurate PV reconstruction with uncertainty estimates, helping distribution system operators better manage grid planning and flexibility.
