Turn every window into a power source.
Transparent solar technology designed for modern cities — generating clean energy without compromising architecture, natural light or urban space.
Cities have a solar problem.
Traditional solar competes for scarce rooftop and ground space. Dense buildings have limited rooftops, growing energy demand, and vast unused glass surfaces.
No Space for Traditional Panels
Rooftop and ground installations require significant usable area that many apartment buildings simply do not have.
The Transparent-PV Gap
Transparent solar technology has historically struggled to match conventional PV efficiency. Reference: ~40% lower efficiency.
Sustainability vs. Architecture
Modern users increasingly expect sustainability and design to coexist. Bolt-on panels compromise both.
Glass Is Everywhere. Electricity Is Not.
Windows, facades, skylights and balconies are surfaces that conventional solar cannot exploit in the same way.
What if the building itself
could generate energy?
Transparent photovoltaics can potentially transform windows, facades, skylights, balconies, glass partitions and other transparent surfaces into photovoltaic surfaces — using architectural space the built environment already occupies.
Consumer
Buildings only draw from the grid. Every window is a passive surface.
Consumer + Generator
Every glass surface participates in energy generation. Architecture becomes infrastructure.
Solar that adapts to the building.
Six design principles that shape every prototype we build.
Transparent
Preserves visual openness and natural light.
Flexible
Adaptive substrates enable non-rigid installation.
Foldable
Origami-inspired architecture for compact deployment.
Compact
Reduces transport & storage footprint significantly.
Aesthetic
Part of the building — not placed on top of it.
Urban-First
Engineered around dense, high-rise environments.
A single panel. Four states.
Interact with our prototype concept — from expanded generation to compact deployment.
Flat.
Expanded panel geometry. Maximum active surface area for photovoltaic capture.
The physics behind transparent solar.
A solar cell wants to absorb photons. A transparent surface wants photons to pass through. LumiFold's research direction is to resolve this tension by harvesting invisible wavelengths.
Engineering the material stack.
Illustrative product architecture — not a validated final commercial architecture.
Closing the efficiency gap.
Development targets — not current validated commercial performance. Design refinement continues throughout every phase.
Every glass surface, active.
Designed for dense cities — where rooftops are scarce and glass is everywhere.
Imagine your building as a power plant.
Toggle between conventional glass and a LumiFold-activated facade. Illustrative visualization — not an engineering simulation.
How much could your building generate?
Illustrative estimate — not an engineering certification. Real-world performance depends on orientation, shading, weather and validated module characteristics.
The competitive picture.
No unsupported superiority claims — just an honest comparison of design directions.
A new surface for solar.
Apartment buildings contain vast areas of untapped transparent surface — the opportunity is to turn those surfaces into energy assets.
