Startup Check – Who’s shaping the future of solar?
pv magazine editor Matthew Lynas toured the startup corner at Intersolar Europe 2025, highlighting emerging businesses focused on flexibility, smart meters, software, and PV integrated with glass.
Roltec plans CIGS solar module factory in Poland
Germany’s Singulus Technologies will provide three of its physical vapor deposition (PVD) vacuum sputtering systems to Poland-based module manufacturer Roltec at a new plant that will produce copper, indium, gallium, and selenium (CIGS) cells on glass substrates.
Scientists build photovoltaic-thermal panel hosting four different cooling techs
Researchers from the Middle East have simulated a novel PV thermal module which includes a thermoelectric generator above the absorber layer, conical helical tape in the cooling tube and a ferrofluid. These technologies reportedly contributed to increased PV efficiency and thermal efficiency by 2.12% and 23.34%, respectively.
Sonnex plan 500 MW solar module factory in Bangladesh
Germany’s Sonnex plans to scale the capacity of its factory in Bangladesh to 500 MW by 2028 and to an unspecified gigawatt scale by 2035.
Heterojunction solar cell based on cerium-doped indium oxide TCO achieves 23.58% efficiency
Researchers at the Delft University of Technology have developed new cerium-doped indium oxides for applications in heterojunction solar cells. A transparent conductive oxide built with the new compound has enabled a considerable increase in power conversion efficiency.
Ecoprogetti releases fully automated solar panel recycling line
Italy’s Ecoprogetti has developed an automated photovoltaic recycling line that separates and recovers up to 100% of the aluminum, copper, glass, plastic and silicon in solar panels. It can process up to 60 panels per hour while using 40% less energy than other solutions on the market.
Bluetti Apex 300 with 2.7 kWh battery pricing now available ahead of launch
Bluetti has now launched the Apex 300 portable power station, bringing a new scalable power solutions for home backup, travel, and off-grid living.
Premier Energies, Sino-American Silicon plan 2 GW solar wafer plant in India
India’s Premier Energies and Taiwan’s Sino-American Silicon Products have signed a joint venture agreement that will see the development of a 2 GW solar wafer manufacturing plant in India.
Is crystalline silicon solar resistant to electromagnetic fields?
Researchers in Burkina Faso have assessed the technical feasibility of PV systems near base transceiver stations and have found that solar modules with “optimal” boron doping levels may better resist the electromagnetic field effects.
2D/3D perovskite solar cell based on dopant-free HTL achieves 25.9% efficiency
An international team of researchers has demonstrated a novel solvent process for pure and highly crystalline 2D perovskites, which they demonstrated in 2D/3D perovskite solar cells. A n-i-p champion perovskite solar cell had a power conversion efficiency of 25.9%, retaining 91% of the initial performance after 1,074 hours at 85 C using maximum power point tracking.
