Abstract

We process a photovoltaic module with 120 half Passivated Emitter und Rear Cells (PERC) that exhibits an independently confirmed power of 303.2 W and a module efficiency of 20.2% (aperture). To the best of our knowledge this is the highest efficiency reported so far for large-area modules using screen-printed p-type PERC solar cells. The cells are optimized for operation within the module. We enhance light harvesting from the normally inactive spacing between the cells and from the interconnector ribbons. Additionally, we reduce the inactive area to below 3% of the module area. Various experimental improvements are analyzed quantitatively.
