Hearthglaze ™

Color-Matched, High-Transmission BIPV Glazing for Shingle Roofs

KEY FEATURES

•Uniform shingle tone at normal roof viewing distances.

• Quantum Dot / Luminescent Light Management — a photonic layer converts and redirects a portion of the incident spectrum toward the cell's peak response, offsetting the transmission cost of the color layer.

• Fired-Glass Durability — color layer is kiln-fused into the cover glass itself — not a film, laminate, or surface coating — for long-term UV and weather stability.

• 25-Year Warranty — covers color stability and structural integrity of the cover glass for the same service life as the underlying solar module.

BUILT FOR ROOFING & SOLAR INSTALLERS

• Faster approvals — reduces aesthetic objections in HOA and municipal permitting.

• Drop-in retrofit — designed as a cover-glass replacement compatible with standard module assembly.

• No visible seams — color pattern is continuous across the panel face, avoiding a tiled or patchwork look.

Hearthglaze ™ is a fired-glass cover for rooftop solar modules that visually blends photovoltaic panels into asphalt shingle roofing, while a quantum-dot and luminescent-material layer maintains high light transmission to the cell beneath. Built for installers who need aesthetic sign-off from homeowners, HOAs, and municipal reviewers without trading away energy yield.

ArgentaCu™

Dual-Side Silver-Coated Copper Metallization Paste for Silicon Heterojunction Cells

Silver has long been the hidden ceiling on heterojunction economics — the single largest driver of cell conversion cost, and a growing exposure to a volatile, supply-constrained precious metal. ArgentaCu™ is engineered to break that dependency.

Built on an advanced silver-coated copper particle system, ArgentaCu™ delivers the low-temperature processability HJT demands while dramatically reducing the silver content per cell. A copper core carries the current; an engineered silver shell delivers the conductivity and contact quality — giving you the performance profile you expect from a premium paste, at a fraction of the silver.

Why ArgentaCu™

Substantially lower silver consumption
A copper-core architecture displaces the majority of silver in every finger, cutting your exposure to silver price volatility and shrinking one of the largest line items in your cell cost structure — without asking you to compromise on output.

One paste, both sides
Formulated for front- and rear-side metallization on a single material qualification. Simplify your bill of materials, streamline procurement, and reduce process complexity across the line.

Drop-in compatibility
Designed for standard low-temperature screen printing. ArgentaCu™ works within your existing metallization infrastructure — no capital-intensive line conversion, no new deposition equipment. Qualify it and run it.

Engineered for stability
A continuous, purpose-designed silver shell protects the copper core, addressing the oxidation and corrosion behavior that matters most over a module's service life.

Fine-line ready
Optimized rheology supports narrow, well-defined finger geometry — helping you recover active cell area and hold the line on shading losses as you reduce metal.
