Contacting of both polarities is achieved by screen printing of a silver paste and contact firing. Contact resistance values are shown to heavily depend on firing set temperatures. In a first experiment, conversion efficiencies up to 20.4% are demonstrated.enPhotovoltaikSilicium-PhotovoltaikOberflächen: KonditionierungPassivierungLichteinfangKontaktierung und StrukturierungPilotherstellung von industrienahen SolarzellenTOPConcontactsLPCVDpolysiliconprinting621530697journal article
