How to reduce ionic losses in tin-based perovskite solar cells
Researchers in Germany have developed a DMSO-free fabrication process for tin-based perovskite solar cells that dramatically reduces ion density – over tenfold lower than in lead-based devices – leading to improved stability.
U.S. research finds PV can support bird, bat activities
A pair of research studies led by the Argonne National Laboratory have demonstrated how “ecovoltaic” installations in the midwestern United States are home to more bird and bat activities than nearby fields used for agriculture.
Insolation Energy advances major solar manufacturing expansion in India
Insolation Energy says construction, equipment procurement, and certification steps across its solar cell, module, and aluminum frame facilities in India are moving ahead on schedule as the company scales national manufacturing capacity.
Africa’s largest off-grid solar-plus-storage project comes online in Angola
In Angola, 75.26 MWh of battery storage has begun operating as part of Africa’s largest off-grid renewable energy system to date.
Acciona Energia completes 380 MW solar project in Australia
Acciona Energia says the Aldoga Solar Farm has entered full commercial operations as Queensland accelerates large-scale renewable buildout.
The thermomechanical impact of plated copper contacts on heterojunction solar cells
UNSW researchers have found that annealing copper-plated contacts in heterojunction solar cells creates only localized stress. Their analysis also showed that, at typical annealing temperatures around 200 C, the probability of silicon fracture is very low.
Industry addresses UV degradation, hail risk in European solar modules
Industry leaders at pv magazine Week Europe 2025 said manufacturers are implementing measures to limit ultraviolet-induced degradation in tunnel oxide passivated contact (TOPCon) solar modules and strengthen resilience to hail damage to protect performance and reduce financial risk.
Oscal launches 1,024 Wh portable storage system
The Chinese company said its Power Max 1800 SE has a rated power of 1.8 kW and a surge power of 2.4 kW. It weighs 15.5 kg and measures 39 cm x 23 cm x 25.4 cm.
Calefa Oy releases waste heat-powered steam heat pump
The Finnish company said its novel AmbiSteam system can produce process steam above 5 bar. It is based on the company’s SteamLevel heat pump technology.
Three US states drive community solar growth in Q3
A new report from the Institute for Local Self-Reliance says non-utility community solar expanded meaningfully in only three US states in the third quarter of 2025 amid uneven policy support.
