The ratio of module power to cell power, multiplied by the number of cells integrated in the module, is defined as the cell-to-module (CTM) power ratio. This factor quantifies the general loss/gain percentage in a PV module , and its importance can be explained by means of an example.
The double glass module design offers not only much higher reliability and longer durability but also significant Balance of System cost savings by eliminating the aluminum frame of conventional modules and frame-grounding requirements. The application of double-glass modules covers multiple markets including utility, residential and commercial.
Results demonstrate that the interplay between encapsulation materials and interconnection technologies significantly impacts the CTM ratio of back-contact cell modules. The study proposes optimized encapsulation strategies tailored to diverse application needs.
For example, it was possible to produce half-cell modules with a CTM of 104 % (module output 256 W) or multi busbar modules with 306 W at ModuleTEC of Fraunhofer ISE with the aid of “SmartCalc.CTM”. The individual gain and loss mechanisms from cell to module are analyzed and purposefully optimized in the “CTM100+” project.
