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.

Sunwoda’s MESS 2000 mobile energy storage vehicle redefines the role of mobile power—evolving from a tool for emergencies to a key player in everyday energy supply.

Enphase Energy has posted $356.1 million in revenue for the first quarter of 2025, falling short of expectations. The solar microinverter and battery storage provider says it has lowered its margin outlook due to rising tariff pressures.

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.

Government-run Sustainable Energy Authority of Ireland (SEAI) is tendering for the provision of technical and advisory support services for its grant programs aimed at organizations in Ireland planning to decarbonize. The tender follows a report by the SEAI that showed Ireland has a limited market for industrial heat pumps and called for greater outreach and support for businesses to install the technology.

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.

Dutch energy storage firm Return has started construction on the 100 MW/200 MWh battery energy storage system in Waddinxveen, which will be the first project of the size to connect to the TenneT Netherlands high-voltage network in 2026. Vattenfall will manage and optimize half of the system’s capacity under an eight-year contract.

The Japanese government says it has opened applications for a subsidy initiative aimed at cutting costs for renewable heat and industrial waste heat systems. The program supports equipment upgrades that lower emissions and improve energy efficiency.
