Screen-Printed Solar Cell Sets New Efficiency Record – 20.2%

The initial attempts produced cell efficiency of well above 19%, but that wasn’t quite good enough. Co-operating with the Schmid Group from Freudenstadt and further supported by federal grants, the SCHOTT Solar team focused on optimizing the front surface of the cell. In the end, it was a combination of Schmid’s production-established selective emitter technology with SCHOTT’s PERC (Passsivated Emitter and Rear Contacts) technology that pushed them over the 20% mark. The final result is an industry standard 156x156mm screen-printed solar cell.
