an unprecedented achievement in solar energy
China’s JinkoSolar has once again revolutionized the solar energy landscape by achieving a new world record in solar cell efficiency. This latest breakthrough involves their tandem perovskite solar cells, now reaching a staggering 33.84% efficiency rate, positioning the Chinese manufacturer at the forefront of photovoltaic technology.
setting new benchmarks with jinkosolar
The Shanghai-based solar module manufacturer, JinkoSolar, has marked a significant milestone by developing an N-type TOPCon perovskite-based tandem solar cell that has achieved a record conversion rate of 33.84%. Independently validated by the Institute of Microsystems and Information Technology in Shanghai under the aegis of the Chinese Academy of Sciences, this cell surpasses the previous record of 33.24% also held by JinkoSolar. This extraordinary progress represents the company’s 27th world record for photovoltaic product efficiency and power.
the science behind topcon technology
The innovative tandem solar cell from JinkoSolar incorporates high-efficiency monocrystalline TOPCon technology as its base layer, enhanced through advancements in full-area passivated contact innovations, interfacial defect passivation of perovskite, and bulk defect passivation. These technological strides have exceeded the conversion limits of traditional monocrystalline silicon cells, affirming TOPCon’s compatibility with next-generation tandem perovskite/silicon cells.
- High-efficiency base layer: Utilizes monocrystalline TOPCon technology.
- Passivation breakthroughs: Includes interfacial and bulk defect passivation techniques.
perovskite materials’ unique advantages
Recognized for their potential to revolutionize solar technology due to high efficiency and lower manufacturing costs, perovskite materials offer unique properties that provide flexibility in design and integration. These qualities make them particularly attractive for next-generation solar applications.
sustainability challenges and commercial applications
A major challenge for adopting perovskites lies in their propensity to degrade over time, raising significant concerns for their use in commercial applications. Solar products, especially those installed outdoors, must withstand harsh weather conditions, temperature fluctuations, and UV exposure over many years, making the development of more durable solutions crucial.
- Sustainability issues: Perovskites tend to degrade over time.
- Environmental resilience: Crucial for outdoor installations facing tough conditions.
a glimpse into future solar technologies
The silicon-perovskite tandem solar cell is seen as cutting-edge technology for ultra-efficient next-generation solar cells, theoretically capable of reaching maximum efficiencies up to 43%. This far exceeds the Shockley-Queisser limit of 33.7% for single-junction cells.
a global race towards higher efficiency
The international photovoltaic industry is witnessing rapid innovation and intense competition. In September 2024, another Chinese manufacturer LONGi set a new world record for perovskite tandem solar cell efficiency at 34.6%, underscoring this competitive spirit. Key players like King Abdullah University of Science and Technology (KAUST) in Saudi Arabia and LONGi continue to push technological boundaries.
- Aim: Achieving efficiencies beyond current limits.
a greener and more efficient future ahead
The global shift towards sustainable energy solutions emphasizes the need for more efficient and environmentally friendly electronic devices. JinkoSolar’s latest advancement could mark a pivotal moment in solar energy production, offering promising prospects for an ever-evolving industry.
