R&D Services

Cell Interconnection

The interconnection of solar cells causes ohmic and optical losses in a module. We use various soldering technologies and industrial stringing equipment for measuring and optimizing the quality of the joints.

Encapsulation

With advanced characterization methods we are able to analyse all aspects of laminate properties. We focus on fast and accurate methods to accelerate product and process development cycles.

Integrated Modules

We develop integrated module designs to meet specific requirements and create tailored product solutions.

Module Efficiency

Solar cells usually suffer from losses when integrated into a module. We analyze the effects down to the material level and assess the potential for optimization.

FEM-Simulations of PV Modules and Components

Finite element method (FEM) simulations can quickly reveal optimization potential of PV modules and their components.

Fraunhofer ISE offers a comprehensive range of services for module product development and materials testing. We provide support for turning innovative ideas into reliable, efficient and competitive products, as well as for improving quality and efficiency in existing module and interconnection concepts.

Our research covers the integration of high-efficiency solar cells, reliable soldering processes, conductive adhesive technology, laminate-free edge-sealed solar modules and the cell-to-module (CTM) power and efficiency optimization.

We are able to develop, improve and test your products to meet industrial demands. Our excellently equipped Fraunhofer ISE Module Technology Center (Module-TEC) supports development from first ideas to module pilot manufacturing.

With SmartCalc.CTM, Fraunhofer ISE has developed a software that helps reduce the cell-to-module power losses in PV module manufacturing.

SmartCalc.CTM is a tool for the fast and precise calculation of cell-to-module losses and gains for solar modules.

The combination of sophisticated scientific models and measured data provide the basis for CTM loss analysis of a wide range of module concepts and materials. An intuitive graphical user interface allows for quick and easy virtual protoytyping.

Industrial stringer for the interconnection of solar cells at Module-TEC

Module-TEC offers extensive facilities to develop module technology. It fills the gap between laboratory development and industrial production technology by allowing relevant charge numbers and formats to be processed. In addition to production and processing technology, numerous analytical facilities are available for quality control. Our research is concentrating on connection technology for crystalline solar cells, integration of high-efficiency cells into modules and the analysis and optimization of module efficiency. In parallel, we are developing application-specific customized modules for building integration (BIPV) and integration into vehicles.
