Scientists from Fraunhofer ISE have sought to utilize epitaxially grown p-type silicon wafers TOPCon rear emitter (TOPCore) solar cells with the aim of reducing production costs and carbon footprint. They claim this combination is paving the way for TOPCore devices that exceed 25% efficiency.Germany's Fraunhofer Institute for Solar Energy Systems (ISE) has proposed the use of epitaxially grown p-type silicon wafers in TOPCon rear emitter (TOPCore) solar cells, which combine tunnel oxide passivated contact (TOPCon) technology with a rear emitter instead of a front-side pn junction. Epitaxially ...Den vollständigen Artikel lesen ...
