Record High for Screen-Printed Silicon Solar Cell - MaterialsViews
Martin Grolms
The Institute for Solar Energy Research Hamelin (ISFH) in collaboration with Singulus Technologies AG have successfully increased the conversion efficiency of screen-printed silicon solar cells from today’s industry typical 17.0% to 18.5% to a record value of 20.1%, as confirmed by an independent measurement from the Fraunhofer ISE. A novel ICP-AlOx/SiNy double layer at the rear side of the solar cell enables the improvement without applying a “selective emitter”. 20.1% is one of the highest...
