Photovoltaic Reliability Workshop Presentation

Bert Thin Films presented results of their copper-based pastes in a poster titled “Durability of Copper Printed Contacts for Silicon Solar Cells” in Lakewood, Colorado.  This poster discussed the durability of silicon solar cells with a screen-printed copper paste that has fired through the SiN layer using a belt furnace. The paste chemistry forms a Cu-diffusion barrier during firing. Details of the paste rheology and firing process were described. Results of the solar cell response after prolonged exposure to dry heat and damp heat tests were also presented. https://pvrw.nrel.gov
