Mastering HJT - Solar technology of the future, already at REC today



Heterojunction solar cell technology (HJT) has revolutionized the way we think about solar energy. At REC, we believe that HJT is a real pioneering technology, which offers various benefits compared to TOPCon:


  • Higher Energy Conversion Rate: HJT cells combine crystalline silicon and amorphous thin-film silicon, resulting in a more efficient capture of sunlight and transfer of electrons in general. This leads to a higher energy conversion rate and improved outcomes for homeowners and businesses.

  • Pioneering Technology: HJT is considered a pioneering technology with significant potential for efficiency leaps in the near future and the best option for future developments such as tandem structures.

  • Long-Term Performance: The majority of today’s TOPCon solar panels come with a degradation of 0.4% per year and 89.X% power after 25 years. REC’s Alpha HJT products guarantee at least 92% power output at year 25, giving consumers and installers greater peace of mind.

  • Heat Loss Reduction: The materials used in HJT cells have a lower thermal conductivity, which leads to higher overall energy output, even in hot climate conditions, thanks to the cell’s low temperature coefficient.

  • Better for the environment: Manufacturing HJT cells requires significantly fewer production steps compared to TOPCon (6 versus 11-14 respectively), and REC’s low temperature production process for HJT cells significantly reduces energy consumption, helping to better protect the environment.



With its Alpha revolution ongoing since 2019, REC has already proven its mastery of HJT technology, increasing panel performance while minimizing environmental footprint.
