Awards

Chengdu, CN - Lighthouse award in Productivity

Sep 2025

A high-volume solar-cell plant, opened in 2020 with semiconductor-grade automation and a large AGV fleet, set out to push productivity further by closing the loop between massive process-data streams and the equipment recipes that drive cell efficiency, yield and consumable cost. The transformation roadmap, drafted during the pandemic, set ambitious efficiency and quality targets and a structured pathway of AI-led use cases — from recipe optimisation to autonomous screen printing, coating control, generative-AI maintenance and unit-level traceability — to deliver them.
