JinkoSolar, the worldwide main PV and ESS provider, has introduced a big breakthrough within the improvement of its N-type TOPCon-based perovskite tandem photo voltaic cell. Examined by the Shanghai Institute of Microsystem and Data Expertise, the cell achieved a formidable conversion effectivity of 33.24%. This enhancement surpasses JinkoSolar’s earlier document of 32.33% for a similar kind of tandem cells, and marks an excellent achievement of breaking the world information for photovoltaic product effectivity and energy 26 instances.
The record-breaking perovskite tandem photo voltaic cell employed Jinko’s n-type high-efficiency monocrystalline TOPCon photo voltaic cell as the underside cell. By way of numerous supplies and expertise improvements together with ultra-thin poly-Si passivated contact expertise, novel light-trapping expertise, intermediate recombination layer with excessive mild transmittance and excessive service mobility, and environment friendly floor passivation expertise utilizing hybrid supplies, a breakthrough in conversion effectivity for the perovskite/TOPCon tandem photo voltaic cell has been achieved. This achievement demonstrates the compatibility of TOPCon as a mainstream photo voltaic cell expertise with the next-generation perovskite/silicon tandem cell expertise, breaking the effectivity restrict of single-junction silicon photo voltaic cell.
As a number one firm within the photovoltaic trade, JinkoSolar invests substantial R&D funds yearly for technological innovation, repeatedly increase its patent numbers and breaking world information in R&D achievements. To this point, JinkoSolar has filed over 3,800 international patent purposes and has been granted greater than 3,500 patents, offering greater effectivity and higher worth power options to the worldwide photo voltaic photovoltaic market with ongoing technological breakthroughs.
Dr. Jin Hao, CTO of JinkoSolar, mentioned, ‘This milestone breakthrough as soon as once more highlights JinkoSolar’s willpower to repeatedly discover the bounds and robust technological innovation capabilities. It additionally lays a strong technical basis for the corporate’s subsequent improvement. We imagine that as we proceed to deepen our scientific analysis and expertise, it can additionally contribute to constructing a greener and extra sustainable new power construction.’
