The Swiss group acquired Gamesa Electric’s power electronics business in Spain from Siemens Gamesa. The financial terms of the deal were not revealed.

Dongkuk CM has introduced an ultra-high-reflectivity color steel sheet designed to boost the performance of bifacial rooftop PV systems, increasing solar reflectance to 80–85. The new material also offers enhanced corrosion resistance, long-term durability, and added cooling benefits thanks to its advanced plating and dual-layer design, according to the manufacturer.

JinkoSolar says it has increased the efficiency rating for its perovskite-silicon tandem solar cells from 34.22% to 34.76%, confirmed by China’s National PV Metric & Testing Center (NPVM).

The Norwegian industrial heat pump specialist said its HoegTemp system has a heat supply capacity of 0.2 MW to 5 MW and a coefficient of performance above 2 at high lifts.

Researchers in China have developed a dipolar passivation method that reduces defects and improves charge transport in solar cells based on narrow-bandgap tin lead perovskite. The approach has enabled the fabrication of all-perovskite tandem solar cells with efficiencies of around 30% and enhanced stability,

Italian research agency Enea has created a web tool that assesses the feasibility of replacing residential gas boilers with heat pumps by providing an estimate of the potential energy and economic savings. The app also provides information on the technical specifications of the photovoltaic system necessary to meet the heat pump’s electricity demand.

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how hydrogenated amorphous silicon passivation help mitigate these defects and improve cell performance.

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 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.

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.
