Swedish scientists build bifacial chalcogenide solar cell with 15.1% efficiency
Researchers in Sweden developed a bifacial chalcoprite solar cell using a titanium-doped indium oxide (ITiO) back contact, achieving 68% bifaciality. The device is able to maintain strong front-side performance with around 15% efficiency, 595 mV open-circuit voltage, and 75% fill factor.”
California bill targets DER access to resource adequacy market
California Senator Josh Becker says proposed legislation would require regulators to allow distributed energy resources (DERs), including batteries and electric vehicles, to participate in the state’s grid reliability market.
Electrospray cooling can boost PV panel performance with minimal water use
Researchers in Turkey optimized electrospray cooling for PV panels, achieving optimal power output with minimal water use and a compact, energy-efficient setup. Their study identified irradiance, flow rate, voltage, and nozzle distance as ideal parameters.
China solar cell prices fall for third consecutive week as upstream costs ease
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Germany classifies cybersecurity threats for energy infrastructure
Germany’s Federal Network Agency will use a new, structured framework developed by Fraunhofer IOSB-AST to classify cybersecurity incidents in the energy sector. The methodology enables comprehensive risk assessments, from initial reports to systemic and economic impacts, supporting consistent evaluation across the entire energy value chain.
Austria deploys 1.63 GW of solar in 2025
Austria’s photovoltaic market slowed in 2025, with around 1,634 MW of new capacity installed, bringing the country’s total PV capacity to approximately 9.9 GW.
German pilot shows 700 EVs can provide redispatch services
TransnetBW says its pilot with Octopus Energy shows 700 electric vehicles can deliver grid flexibility within existing redispatch processes, with potential to scale to gigawatt-hour levels.
Hysolar moves to take control of Suntech
Hongyuan Green Energy (Hysolar) says it plans to take control of Wuxi Suntech Solar Power through a court-led restructuring that transfers core assets into a new entity while isolating legacy debt.
Agrivoltaics for turnips
Researchers in Canada found that semi-transparent cadmium telluride and low-transparency crystalline silicon solar panels can boost turnip root and leaf yields in agrivoltaic systems by optimizing light quality, distribution, and heat stress. Their study highlights that PV module type, transparency, and spectral transmission must be carefully matched to plant physiology to maximize both crop productivity and renewable energy generation.
UK solar deployment hits 22 GW as more large projects commissioned
Government data reveals 2.5 GW of new solar added in 12-months period, the fastest pace for a decade. Deployment expected to accelerate as pipeline of utility-scale projects grows and subsidy support for residential installations kicks in.
