In this PV Tech article, George Touloupas, CEA’s Director of Technology and Quality, and Brian Hansen, CEA’s Director of Supply Chain, discuss the solar industry's shift from passivated emitter and rear contact (PERC) technology to tunnel oxide passivated contact (TOPCon) technology.

The solar industry is undergoing a monumental shift, rapidly moving away from passivated emitter and rear contact (PERC) technology to tunnel oxide passivated contact (TOPCon) technology.

The advantages of TOPCon are clear: higher efficiency, improved energy yield, and significantly lower levelised cost of energy (LCOE) from reduced cabling, land, trackers and labour costs…
