# Swift Solar

> Swift Solar is a San Carlos, California startup building perovskite tandem solar cells that aim to beat silicon on both efficiency and cost. Spun out of Stanford, MIT, Oxford and NREL in 2017, the company is now scaling toward gigawatt manufacturing in the United States after a $27M Series A and the 2026 acquisition of Meyer Burger's HJT manufacturing assets and patents.

- **Founded:** 2017
- **Headquarters:** San Carlos, California, United States
- **Founders:** Joel Jean (Co-founder & CEO), Tomas Leijtens (Co-founder & CTO), Max Hoerantner (Co-founder), Giles Eperon (Co-founder), Kevin Bush (Co-founder), Sam Stranks (Co-founder)
- **Team size:** ~56 employees
- **Products:** Perovskite tandem solar cells, Lightweight & flexible perovskite modules, HJT silicon cells
- **Notable:** Closed $27M Series A in June 2024 co-led by Eni Next and Fontinalis Partners., Won $7M DOE thin-film PV award., Deployed perovskite panels in U.S. Army microgrid field demonstration (2025).

## Products & services

- **Perovskite tandem solar cells** — High-efficiency solar cells stacking a perovskite top layer on a silicon bottom cell to push past silicon's efficiency limit.
- **Lightweight & flexible perovskite modules** — Thin-film solar for vehicles, telecom towers, space, and rooftops where weight and form factor matter.
- **HJT silicon cells** — Heterojunction silicon cells and modules following the 2026 acquisition of Meyer Burger's HJT manufacturing assets and patents.

## Achievements

- Closed $27M Series A in June 2024 co-led by Eni Next and Fontinalis Partners.
- Won $7M DOE thin-film PV award.
- Deployed perovskite panels in U.S. Army microgrid field demonstration (2025).
- Acquired Meyer Burger's HJT manufacturing assets and global patent portfolio (March 2026).
- Six co-founders with combined 80,000+ citations and four Forbes 30 Under 30 fellowships.
