The tandem device is based on a bottom thin-film heterojunction cell that can bend and a top perovskite cell that can be manufactured with a low-temperature process to prevent damage. It achieved the highest efficiency ever recorded to date for a flexible perovskite-silicon tandem solar cell.

Complete Solaria says it acquired SunPower’s assets for $45 million after its bankruptcy, then sold its shingled module patents to Maxeon, which is now owned by China’s TCL Group.

Off-grid solar investment fell 30% in 2024, with early-stage firms and productive-use tech hit hardest, says Gogla. The global association for the off-grid solar energy industry adds that scale-ups attracted 77% of the nearly $300 million invested, signaling stronger commercial viability among mature players.

Chinese manufacturer Das Solar says it will open its first European PV panel assembly plant in Mandeure, eastern France, by the end of 2025.

Austria has opened applications for its €60 million ($68.3 million) rooftop PV rebate program for 2025, with a second-round “Made in Europe” bonus offering 20% more funding for projects using European-made components, says OeMAG.

AleaSoft Energy Forecasting’s latest analysis finds most major European electricity markets recorded negative prices during the third week of April, particularly over the Easter weekend. The Portuguese and Spanish markets saw zero or negative prices across each day last week.

Researchers in Italy have designed a novel carbon dioxide heat pump that can work with photovoltaic-thermal energy, a finned coil heat exchanger and a U-tube borehole heat exchanger. Their experiment has shown that the simultaneous use of at least two energy sources always results in improved system performance even with limited heat transfer areas.

The Japanese automotive components and systems manufacturer began testing its proprietary organic perovskite solar modules in what will be a 30 kW outdoor field trial at one of its facilities in Anjo.

A team of researchers based in Japan and Sweden have found a correlation between higher feed-in tariffs and increased capital expenditures of solar projects in Japan. They suggest this may have led to a lack of incentive for developers to innovate or reduce costs, in turn inflating expenditure and hindering long-term market competitiveness.

The Indian manufacturer said its new n-type TOPCon bifacial solar module has a a power output of 585 W to 620 W and the same compact dimensions as a traditional 550 W panel.
