Jinko Solar Achieves Breakthrough with 33.24% Efficiency
-
Jinko Solar has announced a significant breakthrough in solar technology, achieving a conversion efficiency of 33.24% on its n-type TOPCon-based perovskite tandem solar cell.
The tandem solar cell utilized Jinko’s n-type high-efficiency monocrystalline TOPCon solar cell as the bottom layer. The impressive efficiency was made possible through a series of innovative materials and technology advancements:
1. Ultra-thin poly-Si passivated contact technology
2. Novel light-trapping technology
3. Intermediate recombination layer with high light transmittance and carrier mobility
4. Efficient surface passivation technology using hybrid materialsThese innovations demonstrate the compatibility of TOPCon technology with next-generation perovskite/silicon tandem cell technology.
