HD Hyundai Energy Solutions, an energy subsidiary of HD Hyundai, will launch its new n-TOPCon modules for the U.S. market at the RE+ tradeshow next month. This line includes 108-cell modules for the residential market and 144- and 156-cell modules for the commercial and utility-scale markets. The new n-type modules have efficiencies ranging from 22.3 to 22.9%.
In addition, HD Hyundai Energy Solutions will present its tandem cells and RoHS-certified eco-friendly products. The tandem cells, co-developed by Hyundai with the Korea Institute of Chemical Technology, combine perovskite cells and HJT silicon cells, achieving a theoretical efficiency limit of 44%, significantly surpassing the 29% efficiency limit of traditional crystalline solar cells.
HD Hyundai Energy Solutions will be jointly exhibiting with HD Hyundai Electric to introduce power equipment essential for transmission and distribution.

” The tandem cells, co-developed by Hyundai with the Korea Institute of Chemical Technology, combine perovskite cells and HJT silicon cells, achieving a theoretical efficiency limit of 44%, significantly surpassing the 29% efficiency limit of traditional crystalline solar cells.”
For many homes in the U.S. right now a 506 square foot array on one’s roof can supply something on the order, roughly 22 by 23 feet square would allow 10.4kWp and (IF) this tandem cell structure off of a manufacturing line would allow 30% efficiency, that same array would become 14.2kWp, (IF) this tandem cell product off of a manufacturing line was 40% efficient, then one could have an array of 18.9KWp, a substantial leap in home and small business generation capability on any given day, sunny or cloudy. The burning question is what is the LETID and PID from the first year of use and the degradation each year of use after that.
I understand from this site, the DOE has had grants for such tandem cell development and American company First Solar has been in the hunt for superior tandem cell manufacturing at the Ohio plants, (perhaps) by 2028? This First Solar/Evolar technology ‘stack’ might just get to the point of thin film tandem solar cells at 30% plus sooner than later. First Solar is poised with its previous purchase of company TetraSun TopCon cell manufacturing (IP). I wholly look forward to that day.
The future’s so bright, ya’ gotta wear shades.
