Elon Musk, Chief Executive Officer of Tesla and SpaceX, recently has given a public nod to JinkoSolar’s latest TOPCon efficiency world record. Responding to a social media post about the breakthrough, Musk wrote simply “True,” underscoring global recognition of China’s continuing leadership in solar innovation.
Earlier this month JinkoSolar announced that a solar cell built on its TOPCon technology platform had achieved a certified conversion efficiency of 27.79%, independently verified by the Institute for Solar Energy Research in Hamelin (ISFH) in Germany. This marks the thirty-second time JinkoSolar has set a new world record for both cell efficiency and module output power.
Musk, whose ventures span electric mobility, energy storage and artificial intelligence, closely monitors advanced energy technologies. Rising power demand from data centers in the United States and the expanding role of solar in new applications have kept high efficiency photovoltaics at the center of his attention. JinkoSolar’s TOPCon platform, scalable and fully compatible with next generation perovskite tandem structures, exemplifies the technology pipeline that industry leaders view as critical to the planet’s energy future.
Industry analysts note that future space based energy scenarios, including low orbit communication satellites, orbital solar power stations and off planet data centers, will rely on ultrahigh efficiency, lightweight photovoltaic technologies. JinkoSolar’s successive breakthroughs are laying the technical foundation for those long range goals.
The record setting cell integrates a series of proprietary advances:
- An advanced passivated contact structure that uses a composite passivation layer and refined process conditions, suppressing carrier recombination across the entire cell surface.
- Ultralow optical parasitic absorption techniques that maximize utilization of incoming light.
- A novel metallization scheme that combines innovative metal materials with fine line electrode design, significantly improving collection of photogenerated carriers.
The convergence of these innovations has pushed conversion efficiency to 27.79%, reaffirming TOPCon’s position as the next mainstream cell architecture. Continued efficiency gains from the platform are expected to drive down the levelized cost of electricity and accelerate global decarbonization.This new record amply demonstrates that TOPCon technology still offers vast room for growth and robust vitality, cementing JinkoSolar's leadership position in the N-type era.
As the world’s energy transition accelerates, JinkoSolar’s string of record setting achievements keeps raising the photovoltaic efficiency ceiling and injects Chinese ingenuity into the global drive toward a zero carbon future.
