What does it take to turn next-generation solar technology into a bankable commercial product?

Swift Solar is closing the U.S. heterojunction and perovskite tandem solar cell gap. Dr. Gunter Erfurt, managing director at Swift Solar and former Meyer Burger CEO, joins Tim Montague and John Weaver to explain why U.S. module capacity sits near 50 gigawatts while domestic cell capacity trails at 5 gigawatts.

Following Swift Solar's acquisition of Meyer Burger's technology, intellectual property, manufacturing equipment, and engineering team, Dr. Erfurt shares how the company plans to accelerate U.S. solar manufacturing while preparing for the future of perovskite tandem solar cells. John Weaver presses Erfurt throughout on tariffs and real project pricing, drawing on his own current commercial bid.

The conversation explores why heterojunction (HJT) technology is the ideal foundation for perovskites, why bankability matters as much as efficiency, and how domestic solar manufacturing can strengthen energy security and supply chain resilience.

Whether you're a solar developer, EPC, utility professional, investor, policymaker, or clean energy enthusiast, this episode offers valuable insights into where the solar industry is heading over the next decade.

In this episode, you'll learn:

• Why Swift Solar acquired Meyer Burger's manufacturing assets and IP
• How heterojunction technology supports the future of perovskite tandem solar cells
• Why Swift Solar plans to commercialize HJT modules before launching tandem products
• The importance of reliability, bankability, and long-term module performance
• Why glass-glass solar modules outperform traditional glass-backsheet designs
• How domestic U.S. solar manufacturing is evolving, and why module capacity still outpaces cell capacity by a factor of ten
• The challenges of scaling advanced solar cell manufacturing
• Why the utility scale market is Swift Solar's primary focus
• How electrification is expected to triple or quadruple global electricity demand, and why Tim and Dr. Erfurt believe solar, wind, and batteries scale faster than nuclear to meet it
• John Weaver's pushback on tariffs, grounded in real project pricing, and Dr. Erfurt's counter on how the IRA tax credit shaped domestic manufacturing growth
• What the next five years could look like for solar manufacturing and clean energy

As electrification accelerates and global electricity demand climbs toward a projected tripling or quadrupling in the coming decades, the solar industry faces real pressure to build technology that is efficient, reliable, and ready to scale. This conversation with Dr. Gunter Erfurt, joined by Tim Montague and John Weaver, offers a behind-the-scenes look at what it actually takes to move breakthrough innovations from the research lab into commercial production. From heterojunction technology and perovskite tandem cells to domestic manufacturing, bankability, and long-term reliability, this episode provides valuable insight into the engineering and business decisions that will shape the next generation of solar.
