A pure-Cu busbar finished with a black composite-resin coating and post-tinned for an all-black module aesthetic, while keeping copper's full conductivity and solderability.
Description
For BIPV facades and premium residential rooftops, uniform module appearance and low light reflection are increasingly mandated by architects.
The Black Bus Bar ribbon from Telison is a special ribbon that has black coating on the surface to maintain the consistency of the bus bar with the cell and solar module frame.
The composite-resin coating meets adhesion requirements without flaking. The tin-coated side preserves copper-grade conductivity and solderability, keeping production yield unaffected. In BIPV applications, the dark ribbon significantly cuts reflective glare and helps meet aesthetic and light-pollution requirements increasingly common in premium residential projects.
It offers high adhesion, flexibility, heat resistance and outstanding weatherability. The black bus bar Ribbon is mainly suitable for BIPV (Building-Integrated Photovoltaics) and all-black panel applications.

meeting aesthetic and architectural requirements; also used in C&I projects demanding uniform module appearance
BIPV
Curtain walls, roofs and canopies requiring a seamless, glare-free all-black front side
All-black module
Visual premium for high-end residential and commercial rooftop markets
Scenic PV
Parks, scenic areas and parking lots where environmental harmony is required
Light-sensitive zones
Airports, railways and residential neighborhoods with strict anti-glare requirements
FAQ
Q: Does the black coating reduce conductivity?
A: No. The coating is a surface layer only - current still travels through the bulk copper. Coating thickness 5–15 μm contributes <0.1% to total resistance.
Q: How strong is the market trend for black busbar in BIPV and all-black modules?
A: Strong growth. BIPV and premium residential markets are driving rising demand for all-black modules through 2025–2026 (industry reports project BIPV penetration >18% by 2028). Black busbar is a key enabler.
Q: Is the black coating eco-friendly?
A: Yes - eco-friendly. The coating is an organic composite-resin system.
