This contribution analyses two different module topologies for shingled solar cells that increase module power at normal operation and under partial shading conditions. A bifacial shingled parallel string layout and a bifacial shingled matrix layout are compared in terms of module output by experiment and cell-to-module (CTM) analysis. After verification of the CTM model for modules samples (0.475 m²), a calculation for full size modules is performed. Both shingled layouts, excel in output power and CTMefficiency in comparison to a conventional module. The shingled modules are also compared regarding partial shading response, with the matrix layout showing superior power output in most investigated cases. Finally, the newly developed concept of "SlimLine" module fabrication is introduced, which uses structured encapsulants to simplify shingle cell placement and alignment having the potential of increased assembly speed and reliability.
