Technology and R&D

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.

Scientists from French research institute CEA-Liten have identified hydrogen migration in doped selective layers as the primary driver of UV-induced degradation in silicon heterojunction solar cells. They have also found that combined light and thermal light-soaking treatments can partially restore performance and improve long-term UV stability.

The pilot showcases a reversible solid oxide fuel cell battery and represents the first fully containerized, modular ultra-LDES system to be operated for thousands of hours, achieving more than 200 hours of energy storage capacity.

Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.
