About this organization

Organization Information : Founded in 2014, Bert Thin Films, Inc. develops specialized copper-based metallization pastes for solar cell manufacturing. Their flagship product, CuBert™, is a screen-printable copper paste designed as a direct, plug‑and‑play replacement for silver paste—compatible with existing screen-printing equipment and belt furnaces, without extra process steps. CuBert™ resists oxidation during air-firing and avoids detrimental diffusion into silicon, maintaining device integrity. Recent tests on TOPCon M10 solar cells achieved 24 % conversion efficiency, matching silver-based pastes. With applications across various cell architectures, their tech is tailored for high‑efficiency production, enabling lower costs and scalable deployment. Bert Thin Films focuses on reliable, cost-effective innovations in solar metallization.

Other Information: Bert Thin Films, Inc. is a Louisville-based cleantech startup developing CuBert™, a copper-based metallization paste for solar cells. Designed as a drop-in replacement for costly silver paste, it offers comparable performance, integrates with existing manufacturing lines, and supports high-efficiency TOPCon cells. Backed by over $2 million in DOE, NSF, and industry funding, the company aims to reduce module costs and supply risks. Pilot-scale production is targeted by 2026, with strong technical validation and national lab collaborations already underway.
