Abstract
We present a novel cell concept that combines the tandem cell approach with the PERC mainstream technology. As an interface between Si bottom and top cell, we utilize passivating \text{n} {mathbf {+}}-type polysilicon on oxide (POLO) contacts and a p+ poly-Si / n+ poly-Si tunneling junction. Our full area PERC+ Si bottom cells are fabricated within a typical industrial process {mathbf {sequence\, where\, the\, POCl}}3{mathbf {-diffusion\, and\, SiN}} \mathbf {x}deposition are replaced by the POLO junction formation processes. The implied {mathbf {open\, circuit\, voltage\, iV}} \mathbf {oc} measured on these devices reaches up to 708 mV (684 mV) under 1 sun (under filtered spectrum), respectively.
