LiFT-PV revives solar foil innovation 

A new chapter in lightweight photovoltaics begins with the relaunch of HyET Solar 

HyET Solar’s breakthrough technology in lightweight solar laminates has been revived and sharpened under a new name: LiFT-PV (Lightweight Flexible Technologies – PhotoVoltaics). This restart marks a strategic repositioning for LiFT-PV — centred on deep partnerships, industrial scale-up, and European technology leadership. Building on 20 years of know-how, a proprietary PET/FTO substrate architecture (enabled by a temporary metal carrier foil), and a validated 800mm roll-to-roll pilot line, the company now moves forward with a compact and committed team, a streamlined ownership structure, and the full backing of a long-term investor consortium. The renewed focus: industrial growth and perovskite-enabled innovation. 

New Company – Clear Mission 

LiFT-PV builds on HyET Solar’s technological legacy – the development of ultralight, flexible solar laminates using Roll-to-Roll (R2R) manufacturing. Originally designed for rooftops and facades, this technology is now positioned to unlock entirely new solar applications: mobile energy systems, weak structures, and integration in circular construction and infrastructure. 

“The technology was ready – and now the conditions are too. With LiFT-PV, we’re creating an organization fully focused on scaling-up, technological innovation, and European collaboration.” 

Thierry de Vrijer, CTO of LiFT-PV 

Strategic Focus Areas 

LiFT-PV’s 2025–2027 roadmap is centred around six pillars: 

  • Perovskite substrate development & scale-up – Building the business case and production roadmap for scalable FTO-on-flexible polymer substrates – a key enabling layer for flexible perovskite modules. 
  • GWp-scale thin-film silicon production line – Designing a high-throughput, automated production line based on insights from the 40MWp pilot and our validated foil technology. 
  • Technology optimization & cost reduction – Ongoing improvement of foil performance, material use, and production efficiency to reduce €/Wp and strengthen competitiveness. 
  • Market & business case development (perovskite) – Assessing market potential, supply chain requirements, and cost structure for industrial-scale perovskite laminate production in Europe. 
  • European collaboration & innovation – Strong engagement in SolarNL, LUMINOSITY, and public-private R&D with partners including TNO, TU Delft, TU/e, and others. 
  • IP & innovation strategy – Additional targeted patent filings in 2025 to protect critical process innovations and secure our position in next-generation PV technology stacks. 

LiFT-PV’s R2R platform supports a dual-technology roadmap: 

  • Mature thin film silicon → For lightweight BIPV and lightweight rooftop markets 
  • Emerging perovskite thin film → For next-generation high-efficiency solar foil 

Why This Relaunch Was Needed 

In 2024, as HyET Solar neared key milestones, the technology was ahead of its time — but market alignment and capital timing lagged behind. Rather than pausing, the team acted: adapting the technology roadmap toward perovskite-based innovation and creating a more agile organizational structure. This strategic realignment, supported by a strong investor group, enabled a clean reset — securing IP, retaining the pilot line, and laying the foundation for long-term growth. With a sharper focus on market needs, LiFT-PV is positioned to scale where the future demand lies. 

This wasn’t a rescue – it was a reset. 

And now, it’s time to scale. 

Shareholders & Strategic Support 

This restart was made possible by the continued belief and support of a new consortium of long-term shareholders. We gratefully acknowledge:  

De Engh, Fortescue (Australia), Invest-NL, Lamina B.V., and VP Ventures.  

Their collective vision enables LiFT-PV to operate with technological continuity and a solid financial base for future growth. 

Looking Ahead: Building a Lighter Energy Future 

From its Dutch base, LiFT-PV is re-engaging with research institutes, system partners, and public-private platforms to bring flexible solar into real-world markets. The team combines deep technical knowledge with hands-on experience in industrial design, pilot production, and scale-up strategy. 

“We invite partners to join us – in projects, in markets, in scaling up, and in creating a lighter way  

to generate energy.”
