Transparent
Glazing retains its natural clarity, daylight and view. Energy generation happens without changing what a window is for.

solar windows
for a brighter,
cleaner future.
HoloSolar transforms everyday glazing into a renewable-energy generator using advanced holography. A thin optical layer selectively redirects sunlight towards photovoltaic cells at the edge of the pane — the view, the daylight and the architecture stay intact.
01Invisible energy
Sunlight is everywhere in the experience. The technology harvesting it is almost nowhere in sight.
HoloSolar is not another solar panel. It is a new architectural surface — a pane of glass that continues to behave like a pane of glass, and quietly generates power from wavelengths of light the eye never needed.
02How HoloSolar works
Technical overview — non-confidentialA single optical layer, four quiet steps.
03Product benefits
01 / 06What a productive pane of glass should do.
Architectural
Designed as a surface, not an appliance. HoloSolar dissolves into the façade instead of competing with it.
Efficient
Holographic optical elements selectively redirect useful wavelengths towards edge photovoltaics, using light that would otherwise pass unused.
Adaptable
Compatible with standard glazing formats, from residential windows to large-scale curtain walls and canopies.
Durable
Engineered for the operational lifetime of architectural glazing, with no visible degradation of the transparent surface.
Sustainable
A low-embodied-energy layer that turns an existing building surface into a productive one — no additional land, no additional footprint.
04Applications
Three environments. One quiet surface.
01Residential
Clean energy without changing the character of the home.
Windows continue to look and behave like windows. Occupants keep the view, the light and the architectural intent — the building simply becomes a quiet contributor to its own energy demand.

02Commercial
Productive façades on the buildings we already build.
Curtain walls, atria and glazed offices become active surfaces. HoloSolar integrates with standard glazing systems used across contemporary commercial architecture.

03Agricultural
Generate power above the crops, not instead of them.
Transparent solar roofs and canopies allow useful light to reach plants below, while agricultural structures harvest energy from the wavelengths crops do not use.

05Sustainability
A whole-system view of what solar architecture can be.
01
Energy savings
Capturing and redirecting solar energy could help buildings reduce external electricity demand and manage heat entering through glazed surfaces.
02
Environmental impact
Turning existing architectural glazing into a generator avoids the additional land, mounting hardware and dedicated structures required by conventional installations.
03
Circular materials
The system is designed around a small number of well-understood materials — glass, thin-film optics and compact edge photovoltaics — chosen with end-of-life recovery in mind.
06Technical overview
Non-confidentialWhat sits inside the pane.
A thin photopolymer film recording the interference pattern needed to redirect selected wavelengths. The element is optically clear across the visible band that matters for daylight.
Diffraction is tuned to bands that contribute little to perceived transparency but carry useful energy, so the pane continues to read as clear glass to the eye.
Diffracted light travels laterally within the glazing stack through total internal reflection, arriving at the perimeter with minimal loss.
Compact PV cells positioned around the frame convert redirected light into electricity while keeping the central visible area transparent.
The stack is engineered to fit standard insulating glass unit formats and to be compatible with existing curtain wall and window systems.
