New PERC Efficiency Record Set Using Heraeus Metallization Paste
Heraeus has contributed in setting a world record in solar cell efficiency. Heraeus' front-side metallization paste has been successfully put to use to achieve a record PERC ("passivated emitter and rear cell") efficiency of 21.7 percent. The record cells were processed at the solar cell R&D line at SolarWorld in Freiberg.
Dr. Weiming Zhang, Senior Vice President, Head of Global Sales & Head of Global Innovation for the Heraeus Photovoltaics Global Business Unit, says: "We are proud of our efforts to supply our metallization pastes and research and development expertise in achieving this record performance. Heraeus has several paste formulations that are ideal for PERC applications. We also have the capability to modify our formulations for special cell design characteristics. We feel that our ability to work closely with our partners allowed us to provide a front-side paste that reduced recombination losses at the surface and minimized shading after the metallization process."
Heraeus has a long history of working with leading academic and industrial researchers to increase the performance and efficiency of advanced cell technologies.
