A hybrid back-contact design verified by Germany's Institute for Solar Energy Research Hamelin has pushed crystalline silicon efficiency to 28.29 percent, close to the technology's theoretical ceiling.
Certified by ESTI in July 2026, the result is the latest in a rapid sequence of gains from LONGi's Central Research Institute, which has added more than 1.5 percentage points since mid-2024.
SolarPower Europe's latest outlook shows growth slowing to 12 percent last year, with installations forecast to fall 8 percent to 612 GW in 2026 before climbing again from 2027.
One platform, two milestones: a 28.13 percent cell measured in Hamelin and a 26.4 percent module logged in Colorado extend the Chinese manufacturer's long-term back-contact technology route.
Huasun's G12-132 HJT solar module has reached a new milestone with a power output of 769 watts and 24.75% efficiency, driving innovation in photovoltaic technology.
Research institutes worldwide are working on improving the efficiency and scalability of organic photovoltaics. ISE scientists could now further increase their own world record.
The efficiency was confirmed by Fraunhofer ISE. The cell was manufactured at the factory in Brandenburg an der Havel, eastern Germany. There, Oxford PV is researching new types of perovskite stack cells.
Today, SolarPower Europe released its new Global Market Outlook during The smarter E Industry Days event. The report provides market intelligence for the global solar sector for 2020, and forecasts capacity for 2021–2025.
