JinkoSolar announced that it has reached 23.53% efficiency with its high-efficiency solar module. The previous record (set by JinkoSolar in January 2021) was 23.01%.
The results of this latest test was independently tested and confirmed by TÜV Rheinland.
“It is our long-standing commitment to provide customers with high-quality products that drive energy efficiency and reduce LCOE through technological innovation,” said Dr. Hao Jin, CTO of JinkoSolar. “Every new record achievement demonstrates our R&D capabilities and is great motivation for the invaluable work we do to upgrade industry standards. We are confident that the investments we have made in R&D will lead to more innovative products for higher efficiency and reliability, and leveraged on our extensive global sales network, our leadership will be further strengthened and has positioned us to promote technological progress and green transformation.”
Jinko reached this new efficiency by using TOPCon cell technology fused with the company’s new welding and packaging technology. The module’s design reduces internal resistance losses and improves power efficiency.

This TOPCon type n cell structure has shown up to 25.25% efficiency, this hints that JinkoSolar can ‘tune’ the manufacturing process and get product runs in the 25% efficiency range sooner or later. Right here and elsewhere there have been articles that some ‘new’ under glass coatings have been found that can boost cell output by down converting some light wavelengths from higher wavelengths to lower wavelengths that the solar PV cell can absorb. One can gain another 4% to maybe 8% power output from this conversion. IF JinkoSolar figures out how to make tandem solar PV cells that stack band gaps and could possibly reach 30% efficiency with decades of use with 20% or less degradation over that period of time, then another leap in solar PV technology will push it out in front on many other possible types of energy generation.
