We make full use of the metamodel and optimize the rear contact distance in each simulation by defining it as a free variable. PERT solar cells are simulated respecting free carrier absorption at the boron doped back surface field (BSF). As a result, PERC cells show the highest overall efficiency at a low base resistivity of r b = 0.5 Ocm, whereas for r b > 1.5 Ocm PERT cells exceed the efficiency of the respective PERC cells.enPhotovoltaikSilicium-PhotovoltaikDotierung und DiffusionOberflächen: KonditionierungPassivierungLichteinfangMesstechnik und ProduktionskontrollemetamodelPERCPERTsimulationQuokka3621697conference paper
