Abstract

In this paper we present a process for the fabrication of interdigitated back contact (IBC) solar cells on multi-crystalline silicon substrates. The process was tested on 1 Omegacm p-doped CZ wafers with a thickness of 180 mum. All process steps used were compatible with industrially established, low-cost production technologies. The process is designed to minimize thermal load on the wafers and is thereby well suited to multi-crystalline silicon substrates. The cell performance was limited by their fill factor due to incorrect firing parameters of the screen printed metallization
