Germany’s Institute for Solar Energy Research Hamelin (ISFH) has announced that its Calibration and Test Center (CalTeC) now offers calibration services for large-area perovskite-silicon tandem solar cells. The expanded capability supports devices up to the G12 wafer format (210 × 210 mm), addressing the growing need for reliable efficiency measurements as tandem technologies move from lab-scale research to commercial development.

Researchers from Xi’an University of Architecture and Technology, Xidian University, Xi’an Jiaotong University, University of New South Wales, Beijing University of Posts and Telecommunications and Ningbo Weiyuan Optoelectronic Research Institute have developed a machine learning-assisted screening strategy to identify lead-free double perovskite materials tailored for agrivoltaic applications, where photovoltaic performance must be balanced with crop light requirements.

TCL Zhonghuan has completed its strategic acquisition of a controlling stake in Yidao New Energy in Quzhou, Zhejiang Province, and used the handover ceremony to unveil three high‑performance TBC and perovskite tandem module products aimed at next‑generation, vertically integrated PV manufacturing. The acquisition positions TCL Zhonghuan to operate an integrated ecosystem covering silicon wafers, high‑efficiency cells and advanced modules within a single industrial chain.
