Cell Interconnection

The interconnection of solar cells causes ohmic and optical losses in a module. In our Module-TEC 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.

Customized Modules

We develop customizable 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.

 

Module-TEC

Software Reduces Losses in Solar PV Modules

Blog post by Max Mittag

Max MittagA photovoltaic module consists of many interconnected solar cells. One cannot say, however, that the module power is simply the sum of the individual cells. Power losses due to reflection, absorption or electrical losses come about in the integration process. These cell-to-module, or CTM, losses have a large effect on the subsequent module performance and can vary greatly depending on the type of solar cell, material or module design. We at Fraunhofer ISE have created a model based on different material parameters in order to calculate these variations. With SmartCalc.CTM, we have developed a software program that makes PV modules (even) more efficient.
