Abstract :
A design concept supported by numerical device modeling is presented for a p-type IBC cell with screen-printed aluminum for both contact polarities. Applying such a design to Cz silicon appears to offer cell efficiency exceeding 20%. The key enabling feature for this design is cleaving each cell into strips held together by tape. These strips are then connected electrically in series using extrusion printing after the strips are laminated to the module glass. The resulting module technology is called SPLICE, for “Screen Printed Locally Interdigitated Contact Elements”.
