Commercial modules with shingled solar cells are currently available on the market [7,8], with a projection trend indicating an increasing market share in the upcoming years .
Purpose and approach of the work Shingling technology for c ll interconnection in a module is not new in photovoltaics (PV): in fact, it was one of the first methods used to create the series between the strings, for example it was ad pted in arly space applications .
a comparison of a parallel-stringing topology with a matrix topology of the cell interconnection. The reduced form factor of shingled solar cells makes them very appealing and effective for use in integrated module products, which is demonstrated by a successful automotive application, additionally profiting from the high p attained.
Furthermore, like many other PV module advancements, shingling can be combined with glass-glass and bifacial techniques. Since more of the module can be covered by solar cells, shingling is a very suitable method for bifacial modules.
