CerCoat _ New CERamic sputtering targets manufactured by SPS using tailored powders for TCO COATing deposition

Important results from the project

The goals of producing powder and sintering sputter targets have been met for AZO but not for ITO. Midsummer has successfully developed optimized recipes for top contacts using the new materials. The Cercoat targets have yet to achieve higher performance than commercial targets. Nevertheless, processes with potential to cut the top contact cost by over 50%, while retaining performance, have been identified. Preparatory tests indicate that the new modules will meet the certification requirements.

Expected long term effects

The lower production costs which can be achieved through the newly optimized top contact is expected to lower the total module price by 2%. However, additional investments for production adaptation and certification are expected during an initial phase. Lower manufacturing costs is expected to generate increased sales of Midsummer’s modules with 2% . The project is expected to generate 2 new job openings over the coming 5 years.

Approach and implementation

The arrangement with a small group of partners focusing on powder synthesis, sintering, analysis and final products has largely been working well. High level of expertize has been present in the group and the dialog has been open and helpful. It has been possible to make adjustments to the plan, when needed, during the course of the project. Focus has been put were the potential was believed to be the greatest. The most important adaptation has been the transition to focus on AZO.
