Indian scientists build 4T perovskite-silicon tandem cell based on hybrid heterojunction PV device
A research group in India has embedded a hybrid heterojunction solar cell as a bottom device in a four-terminal perovskite-silicon solar cell using a solution processing technique. The novel cell architecture, according to its creators, could be produced at significantly lower costs compared to conventional perovskite-silicon tandem designs.
Ecoprogetti supplies US solar panel maker with 800 MW production line
Ecoprogetti has supplied US solar manufacturer CS Solar MFG LLC with an 800 MW production line to produce bifacial glass-glass passivated emitter rear cell (PERC) panels with over 22% efficiency.
Sun-tracking photovoltaics for stadiums
Researchers in Italy have developed a sun-tracking PV system design for stadium covers. The proposed approach is said to offer both strong structural response and high energy yield compared to systems based on fixed structures.
Hamworthy presents new air-source heat pump series
The Tyneham 290HT heat pump is intended for applications in commercial buildings. It uses propane (R290) as the refrigerant and has a coefficient of performance of up to 4.94.
Key takeaways from Sunrise Arabia 2025
A recent joint event by Solarabic and pv magazine in Riyadh highlighted Saudi Arabia’s rapid push for clean energy and localization, with new factories and large storage projects taking shape.
Utrecht wastewater plant launches largest heat pump in Netherlands
Innomotics, Eneco, and Johnson Controls have energized a large-scale heat pump at a municipal wastewater treatment plant in Utrecht, the Netherlands. The system has four heat exchangers, each equipped with two compressors.
Perovskite-silicon tandem solar cell based on hole selective monolayers achieves 29.8% efficiency
Researchers from Fraunhofer ISE and KAUST built a perovskite-silicon tandem solar cell that reportedly offers improved reproducibility. The device relies on self-assembled monolayers that result in low parasitic absorption and rapid charge extraction.
Serbia awards 645 MW in second renewables auction
Serbia has allocated 645 MW across 10 wind and solar projects in its second renewables auction, setting average prices at €0.0509 ($0.0533)/kWh for solar and €0.0535/kWh for wind. The government said the rates are well below market levels.
‘Solar module prices will soon go back to over $0.12/W’
The global solar module industry is expected to regain a sustainable balance in the next six months, Yana Hryshko, head of Solar Supply Chain Research for Wood Mackenzie, told pv magazine. She explains why solar module prices may increase soon, suggesting that Tier 1 modules prices could reach $0.14-$0.15/W by the end of this year, and discusses how consolidation is materializing within the global PV industry.
New algorithm for fault detection in renewables microgrids
An Iraqi-Canadian research team has created a new algorithm that can detect direction change in the line current of renewables-based microgrids. The novel approach can be applied to both grid-forming and grid-following infrastructures.
