Plenitude tests perovskite-silicon tandem solar modules in utility-scale installation pilot
The Italian renewable energy company said it will validate Swift Solar’s 28% efficiency perovskite-silicon tandem technology in a utility-scale project.
Nexwafe secures cash injection from EU scale up funding
German solar wafer manufacturer Nexwafe is one of eight companies receiving investment in the latest round of the European Commission’s Strategic Technologies for Europe Platform (STEP) Scale Up call, an initiative addressing a market gap in deep tech funding in Europe.
Longi achieves 33.35% efficiency for flexible perovskite-silicon tandem solar cell
The Chinese manufacturer said the tandem device was developed through a dual-buffer layer strategy that improves interfacial adhesion while preserving efficient charge extraction. The efficiency result was certified by the US Department of Energy’s National Renewable Energy Laboratory (NREL)
South Korea sets 2030 goal for perovskite-silicon tandem solar panels
South Korea has allocated KRW 33.6 billion ($22.8 million) for R&D on perovskite-silicon tandem solar technology with a goal of commercializing 28%-efficient modules by 2030, according to the Ministry of Economy and Finance.
ChasingLight Technology launches indoor organic PV modules
The China-based organic photovoltaics manufacturer has launched a line of indoor PV modules suitable for integration into digital office products and electronic devices.
Photonic curing could accelerate transition to copper-metallized solar cells
Researchers in the United States have developed a photonic curing technique using laser sintering to rapidly heat and cure copper pastes on temperature-sensitive solar cell substrates without causing thermal stress. The process purportedly produces dense, low-porosity copper layers with strong adhesion to indium tin oxide, achieving low bulk and contact resistivity.
India posts record 4.9 GW of rooftop solar additions in first nine months of 2025
India installed 4.9 GW of rooftop solar capacity in the first nine months of 2025, including 2.1 GW in the third quarter, with cumulative capacity reaching 18.6 GW, according to Mercom India.
Somalia launches tender for solar-storage systems at health facilities
