JinkoSolar, a global leader in solar module manufacturing, has announced a significant advancement in photovoltaic efficiency, setting new benchmarks for its N-type TOPCon technology. The company's independently developed N-type TOPCon modules have achieved a maximum conversion efficiency of 25.58%, a figure independently verified and certified by TÜV SÜD. Concurrently, its 182N-type monocrystalline silicon cell, also based on TOPCon architecture, recorded an impressive full-area conversion efficiency of 27.02%, as validated by the National Photovoltaic Industry Metrology and Testing Center. These breakthroughs underscore the rapid evolution of N-type technology and its increasing dominance in the high-performance solar market.

The remarkable efficiency gains are attributed to a suite of sophisticated technological innovations implemented across both cell and module production. On the cell side, JinkoSolar has leveraged advancements such as metallization laser enhancement, high-quality emitter passivation, and local absorption passivation contact. These techniques collectively minimize recombination losses and optimize current collection, leading to higher power output. For the modules, key innovations include integrated film graphic technology, SMBB (Super Multi Busbar) ultra-multi-main grid technology, and reflective film technology. The SMBB technology, in particular, reduces resistive losses and enhances light capture, while reflective films further improve light utilization within the module structure.

Looking ahead, JinkoSolar is poised to significantly scale up its advanced manufacturing capabilities. The company plans to upgrade over 40% of its existing production capacity this year, with an ambitious target of establishing 40-50GW of high-power TOPCon capacity by the end of 2024. This strategic expansion is designed to meet the escalating global demand for high-efficiency solar solutions. The latest generation of high-efficiency TOPCon capacity is capable of producing modules with a maximum power output of 670W, achieving a module efficiency of up to 24.8% and an impressive bifaciality of 85%. These specifications represent a substantial performance premium, offering approximately 10% higher output compared to traditional TOPCon products.

Company representatives emphasized that these continuous innovations in N-type TOPCon mainstream technology, coupled with aggressive capacity upgrades, position JinkoSolar to accelerate industry-wide capacity clearance. This move is crucial in supporting "anti-involution," a term referring to the industry's need to avoid stagnation and diminishing returns by consistently pushing technological boundaries. By driving higher efficiency and lower levelized cost of energy (LCOE), JinkoSolar aims to promote sustainable long-term development across the solar photovoltaic sector, solidifying N-type TOPCon as the prevailing technology for the foreseeable future and driving further market consolidation towards advanced solutions.
