Flexible Substrate Handling for CIGS Process

The Situation

The CIGS thin film solar photovoltaic process is often implemented on flexible substrates. While these substrates are chosen for their extremely low cost, the handling of them requires special techniques. A leading CIGS PV startup required an extremely high speed, precise assembly system that could reliable handle and place flexible substrates.

The Challenge

Owens Design worked collaboratively with the client to analyze multiple concepts. Tradeoffs between configuration, factory integration, throughput, and cost were considered. An innovative mechanism was developed to rapidly singulate the substrates and align them to the required dimensions. Placement accuracy of 25 um was achieved and throughputs in excess of 1,000 parts per hour were obtained. Owens Design completed the system by developing the software and controls including the HMI and factory interface. The resulting system delivered outstanding results for the client.
