The Heterojunction Silicon Wafer Solar Cell Group develops advanced solar cell architectures and related processes for manufacturing that are capable of cost-effectively realising very high (~25%) PV efficiencies on thin (< 150 microns) industry-size Cz silicon wafers. The group is operating an industrial pilot line for full-size heterojunction and all-back-contact silicon wafer solar cells, including inductively coupled plasma deposition and advanced copper metallisation methods. Selected research topics of the group include advanced heterojunction stacks, all-back-contact solar cells, inkjet printing, inline plating, femtosecond (fs) laser processing, ion implantation, and low-cost alternative TCOs.
