A world-unique solar cell production system
The Midsummer DUO is a turnkey production system for mass production of CIGS solar cells without cadmium. Designed for high capacity, reliability, scalability and superior material use, the Midsummer DUO is at the forefront of flexible thin film solar cell manufacturing. As a customer you have the opportunity to test your machine and verify the performance in our factory before delivery.
Thanks to our unique process, we offer one of the lowest manufacturing costs for high-efficiency solar cells already in small-scale production. Our 156 × 156 mm steel substrates pass sequentially through 25 separate process chambers. The production cycle time is in the order of 20 seconds, meaning one cell is completed every 20 seconds.
The Midsummer DUO tool deposits the complete material stack in an unbroken vacuum chain, which minimizes the risk of contamination. The unbroken vacuum chain allows for less stringent clean room conditions.
Each solar cell has a unique ID which gives access to a large amount of process data for each individual cell. This enables continuous quality control and process development, which is a security for the customer.
