Major PV materials supplier Heraeus has said that its front-side metallisation paste has been used at SolarWorld’s R&D line in Freiberg, Germany to produce PERC cells with a record conversion efficiency of 21.7%.
Dr. Weiming Zhang, senior vice president, head of global sales and head of global innovation for the Heraeus Photovoltaics Global Business Unit, said: “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 metallisation process.”
The company is launching several new metallisation pastes at EU PVSEC next week.
