[SMM PV] China's silicon-based perovskite tandem cell mass-production line was put into operation, with PV conversion efficiency surpassing 31.2%

Published: Jun 15, 2026 18:10
On June 12, a leading PV enterprise officially commenced production of a new-generation perovskite tandem cell line, achieving a stable mass-production conversion efficiency of 31.2%, significantly surpassing the theoretical limit of traditional crystalline silicon cells. By improving encapsulation solutions, the enterprise resolved the perovskite degradation issue, enabling module outdoor service life to reach 30 years. Large wind and solar power bases in western China have already secured initial procurement intentions. The adoption of this new technology will reduce the levelized cost of PV power generation over the long term, driving rising demand for high-end PV auxiliary materials and encapsulation films.
