At this week's Intersolar Show in San Francisco (July 9-12, 2012), imec presents a 20.04% large-area industrial-level silicon solar cell (certification results from Fraunhofer ISE-Callab). The cell combines a high efficiency with a low-cost industrial process.
Imec's proprietary PERC process maximizes the conversion efficiency of the cell through structure and material optimizations while maintaining cost effective device concepts and processing. Imec's PERC-cell is compatible with the requirements of industrial photovoltaic production. It is a large-area (125x125mm2) Cz p-type silicon cell with a simple homogeneous emitter and Ag-single screen-printed front side contacts (65µm finger width), two busbars and an adapted Nc ypzn-evdy gaftebsgcqqrh.
