- JinkoSolar has once again pushed the boundaries of solar technology, announcing a new world record conversion efficiency of 34.76% for its N-type TOPCon-based perovskite tandem solar cell.
- The achievement, certified by the National PV Metric & Testing Center (NPVM), surpasses the company’s previous record of 34.22% and marks the 32nd time JinkoSolar has set a world record in cell efficiency or module power.
According to the company, the milestone reflects major breakthroughs in its tandem and perovskite research programs. Engineers credited the new efficiency level to several innovations, including a self-developed high-efficiency N-type TOPCon bottom cell, improved defect passivation at the perovskite interface, next-generation crystallisation techniques, and enhanced strategies for vertical charge transport. Together, these advances strengthen the technical foundation needed for commercialising high-efficiency tandem solar cells.
Dr. Hao Jin, Chief Technology Officer at JinkoSolar, said the latest result underscores the company’s leadership in next-generation PV technology.
“This 34.76% efficiency breakthrough is a milestone for JinkoSolar’s R&D system, proving the feasibility and great potential of TOPCon and perovskite tandem technology,” he said. “We believe tandem technology will be the next disruptive direction following TOPCon. Our focus now is to move from laboratory success to large-scale application, delivering high-performance, cost-effective, long-life modules to accelerate the global transition to green energy.”
The record reinforces JinkoSolar’s position at the forefront of solar innovation as the industry moves toward tandem architectures expected to define the next era of photovoltaic development.
