At our Concentrator Technology Evaluation Center (Con-TEC), we develop assembly and interconnection technologies as well as manufacturing processes for advanced photovoltaic systems. Our work covers applications ranging from concentrator photovoltaics (CPV) and thermophotovoltaics to optical power transfer and dense array receivers for CPV tower power plants.
A particular focus is on integrating high-performance components into robust systems. Under highly concentrated radiation, extreme thermal and mechanical stresses occur, so that reliability is largely determined by the quality of the assembly and interconnection technology. In particular, the thermal coupling of the components, the stability of the interconnection points , and the long-term durability of materials and optical components are crucial for superior performance and a long service lifetime.
We develop scalable manufacturing processes across industrial value chains – from assembly design through high-precision assembly and bonding to module and system integration. Our infrastructure enables the production of prototypes and small batches under near-industry conditions, as well as the evaluation of new materials, designs, and processes.
We verify the reliability of our systems through comprehensive accelerated aging tests and detailed material and component characterization. Combined with modeling and simulation, this yields a deep understanding of degradation mechanisms, which is specifically applied to the optimization of designs and processes.
In this way, we support our partners in transforming innovative high-performance components into durable, economically producible products.
