What they do

Their core work

Sol Voltaics AB is a Swedish deep-tech SME commercializing nanowire-based solar cell technology — a manufacturing process that deposits semiconductor nanowires onto conventional solar cells to improve light absorption and efficiency without replacing existing production lines. Their core intellectual property centers on aerotaxy, a gas-phase growth technique for producing gallium arsenide nanowires at scale. They bridge the gap between advanced III-V semiconductor research and industrial photovoltaic manufacturing, positioning themselves as a technology supplier to solar cell makers rather than a panel manufacturer themselves.

Core expertise

What they specialise in

Nanowire solar cell fabricationprimary
2 projects

Both Nano-Tandem and NanoSol are built around nanowire photovoltaic technology, with NanoSol explicitly focused on commercializing Sol Voltaics' proprietary nanowire deposition process.

Tandem photovoltaic architectureprimary
1 project

Nano-Tandem (2015–2019) investigated nanowire-based tandem solar cell configurations designed to exceed single-junction efficiency limits.

1 project

NanoSol was funded under the SME Instrument Phase 2 scheme — the most competitive EU commercialization grant — confirming Sol Voltaics' ability to execute a business-scale technology transition plan.

III-V semiconductor materials for photovoltaicssecondary
2 projects

Nanowire solar cells using gallium arsenide and related III-V compounds are the underlying material science across both projects.

Evolution & trajectory

How they've shifted over time

Early focus
Nanowire tandem solar cell research
Recent focus
Nanowire photovoltaic commercialization

Sol Voltaics entered H2020 as a research participant in Nano-Tandem, exploring the scientific viability of nanowire tandem architectures alongside academic and industrial partners. Within a year, they had advanced sufficiently to lead their own SME Instrument project, NanoSol, focused explicitly on accelerating commercialization — a sharp pivot from exploratory research to market entry. This compressed trajectory, from consortium participant to solo project coordinator with a €1.74M grant in under two years, suggests a company that moved quickly through TRL stages and was already engaging industrial customers during the project period.

Sol Voltaics was on a clear trajectory toward industrial scale-up and licensing of their nanowire deposition technology to solar cell manufacturers — though their post-2019 status should be verified before assuming current activity.

Collaboration profile

How they like to work

Role: consortium_leaderReach: European5 countries collaborated

Sol Voltaics demonstrates a dual collaboration mode: joining larger research consortia as a specialist technology contributor when early-stage science is needed, and leading smaller, focused projects when commercialization is the goal. Their SME Instrument project (NanoSol) was coordinator-led, which means they are comfortable owning the business case and managing EU project obligations independently. With only 6 unique partners across 2 projects, they work in compact, focused consortia rather than broad networks.

Sol Voltaics has collaborated with 6 unique partners across 5 countries, a small but internationally spread network consistent with a focused deep-tech SME building targeted research and supply-chain relationships rather than broad academic networks.

Why partner with them

What sets them apart

Sol Voltaics occupies a rare niche: they are not a solar panel manufacturer and not a pure research lab, but a technology platform company whose product is a manufacturing process that improves any silicon solar cell's efficiency by adding a nanowire layer on top. This makes them a potential technology licensor or process equipment supplier to the entire photovoltaic industry. A Lund-based spinout with roots in academic nanoscience, they combine IP ownership with EU-validated commercialization capability — a combination that is genuinely uncommon among European solar SMEs.

Notable projects

Highlights from their portfolio

  • NanoSol
    Coordinated as lead organization under the highly selective SME Instrument Phase 2, receiving €1.74M specifically to commercialize nanowire solar cell technology — the largest and most business-focused grant Sol Voltaics has held.
  • Nano-Tandem
    Participation in this multi-partner research project on nanowire tandem cells placed Sol Voltaics alongside academic and industrial leaders in advanced photovoltaics, validating their technology at a scientific level before their own commercialization push.

Analysis note: Only 2 projects in a narrow 2015–2016 window, both concluding by 2019. The profile is coherent and the technology focus is clear, but there is no post-2019 H2020 data to confirm current activity or whether commercialization succeeded. Verify company status before initiating contact — deep-tech solar SMEs from this period have variable survival rates.
