Wood Mackenzie highlights a groundbreaking 5.2 GW solar-plus-storage project in the UAE capable of delivering 1 GW of continuous baseload power, signaling a potential shift in renewable energy deployment despite high costs. The report also forecasts strong global solar growth through 2030, including the rise of residential “balcony solar” in the U.S. and expanded solar shares in Asia Pacific and the U.S.

A research team from Osaka Metropolitan University have developed a donor-acceptor-donor molecule that can spontaneously self-assemble into nanoscale structures and offer a more stable route to built-in p/n heterojunctions in organic solar cells.

A Chinese-Swedish research team has boosted the performance of tin-lead perovskite solar cells by modifying additives and post-treatment processes. The device also demonstrated improved stability, retaining 60% of its initial efficiency after 550 hours at 85 °C under maximum power point conditions.

With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.

A report from McKinsey and Company says the relative ease of building out solar projects means the U.S and Europe are likely to meet their end-of-decade deployment targets, despite current pipeline gaps of around 205 GW and 181 GW.

Spanish tracker manufacturer Solar Steel has introduced an upgraded 2P single-row tracker designed to simplify assembly, improve standardization, and support deployment on complex terrain, including agrivoltaic projects.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial (C&I) applications, and a liquid-cooled energy storage system.

Scientists have conducted a six-sphere literature analysis of agrivoltaics, considering sustainability, soil–crop productivity, socioeconomic resilience, solar power generation, spatial efficiency, and species. They found that, under optimal terms, agrivoltaics may generate over $1 trillion in added global agricultural income.

IEA-PVPS Task 15 has launched its first modeling intercomparison exercise on coloured building-integrated photovoltaics (BIPV) and is inviting PV modelers and researchers to evaluate their methods using real-world performance data.

Output from Estuary Power’s recently-completed Escape Solar and Storage project more than doubles MGM’s share of solar energy.
