A new pilot research facility for HJT and selective contact solar cells - PV-TEC SELECT

After 10 years of operation of its Photovoltaic Technology Evaluation Centre PV-TEC Fraunhofer ISE recently significantly expanded its research capabilities with the opening of a new pilot research facility for selective contact solar cells - PV-TEC SELECT. PV-TEC SELECT aims to address major challenges on the way to industrialize high efficiency solar cell concepts like Heterojunction (HJT) or TOPCon technology. In this context, the paper introduces the new research facility with its unique equipment setup and process environment (Clean room class 1000 on more than 800 m²). The development of a robust base line process allows Fraunhofer ISE to expand its research offerings for PERC solar cells to next generation high efficiency cell concepts like HJT and TOPCon.
