SCHOTT Solar Achieves Nearly 20% PV Efficiency Using New Fabrication Technology

It will no longer be necessary to use expensive silver in cell manufacturing if long-term stability can be demonstrated successfully, according to SCHOTT. Several innovative technologies were employed in achieving the latest results. In addition to using nickel-copper plating on the front side of the silicon solar PV cells. SCHOTT also employed ‘bleeding’, moving toward leading, edge PERC (Passivated Emitter and Rear Contact) technology to fabricate the cells. An alternative to screen printing of solar cells, PERC essentially increased the efficiency of solar cells by enabling it to capture reflected light from the cell’s backside.
