Abstract

Shingled string photovoltaic (PV) cells have a larger active area, and they significantly reduced damage from the interconnection process using electrically conductive adhesives. This new method using a shingled design provides increased PV module power compared with the conventional PV module for the same installed area. In this work, we study the optimization of shingled string PV cells for high-power shingled design modules (SDMs). To successfully fabricate shingled string PV cells and high-power SDMs, we adjusted the overlap width between solar cells and achieve conversion powers of 406.5 W for a 1100 mm × 1980 mm area. Finally, we perform a reliability tests to verify the durability of our SDMs.
