TKI Urban Energy project COMPASS finishes with record breaking solar cell

To maintain a competitive edge in Dutch solar cell know-how and equipment manufacturing, the goal of the COMPASS project was to explore, combine, and demonstrate high-performance and manufacturability of novel, high-potential passivating contact materials, developed in the Netherlands.
Novel passivating contact stacks and conductive layers developed by ECN, TU Eindhoven, TU Delft, AMOLF, and Solmates have been tested by replacing parts of well-controlled device structures, such as silicon heterojunction (SHJ) solar cells. At Solmates, Levitech and ECN, a first optimization of these novel thin film processes was performed in industrial tools to test the industrial applicability. 
Combining the efforts from all project partners, a process for manufacturing a 6-inch moly-poly solar cell has been developed. Such a solar cell has a front side contact based on a metal oxide (Molybdenum oxide) and a rear side contact based on n-type doped poly-Si. These efforts resulted in a new world record for this moly-poly type cell concept, not only in terms of efficiency (18.1%) but also in cell area size (6-inch square). 
The targets of the TKI Urban Energy are a sustainable infrastructure and a reinforcement of the knowledge position. The COMPASS project has contributed towards reaching this goal through the generation of Dutch knowledge that will lower the production costs of highly efficient solar cells and rigorously simplifies the solar cell production process. This lowers the price of solar energy. Furthermore, in the context of the COMPASS project, solutions have been found based on equipment that is being developed in the Netherlands, which reinforces both the knowledge position and the Dutch economy.
