Renolit showcases reflecting cool roof membrane for bifacial rooftop PV
Renolit France has introduced the Alkor Bright reflective membrane for bifacial rooftop PV systems, offering high solar reflectivity and durability for flat or pitched roofs. The membrane helps keep buildings cooler while boosting the energy output of bifacial solar modules.
France’s S’tile offers custom PV modules for repowering, revamping
S’tile has launched fully customized solar modules for repowering and revamping rooftop PV systems, providing exact-fit replacements or higher-output upgrades tailored to each project.
Indonesia’ Pertamina to build 50 MW flexible PV production line in Indonesia
PT Pertamina Power Indonesia and HyET Solaris Netherlands are planning to construct a 50 MW pilot factory manufacturing the Dutch company’s lightweight and flexible PV products in Indonesia, with ambitions to scale-up to a GW-size manufacturing facility.
Ciel & Terre unveils new floating solar solution
The new floating PV structure removes traditional maintenance walkways between module rows to enable more solar modules to be installed per hectare. Ciel & Terre has also developed a motorized trolley system capable of rolling over the structure.
Sunwafe secures land for 20 GW silicon wafer plant in Spain
Sunwafe says it has formally applied to reserve land in Asturias, Spain, for a 20 GW silicon wafer and ingot factory backed by Chinese capital, EIT InnoEnergy, and a €200 million ($232.6 million) Spanish government grant.
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.
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.
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.
