Three‐dimensional multi‐ribbon interconnection for back‐contact solar cells

Abstract Back‐contact solar cells are an interesting technology with advantages over traditional two‐sided cells. A lack of standardized and low‐cost interconnection methods inhibits their market penetration. In attempt to overcome this obstacle, work introduces technology, based on a fabric encapsulant incorporated metal ribbons. The is tailored for application by adding glass fibres thermoplastic polyolefin. For encapsulant, characterization experiments were conducted results viscosity coefficient thermal expansion shown. Initial reliability testing sample‐size modules high‐efficiency interdigitated back‐contact (IBC) shows promising results, passing up four times the IEC 61215 standard cycling.
