“…This could be due to the metal being deposited at the location where hydrogen blistering occurred. Therefore, it showed that the series resistance increased due to the lifting of the metal and the direct contact on the Si interface, and the parallel resistance decreased as the non-uniform n + polysilicon layer was formed [22]. In order to confirm the blistering phenomenon, Nemeth et al confirmed that the device deteriorated as the metal penetrated the poly-Si through the PL images [23].…”

Tunnel oxide passivated contact (TOPCon) solar cells are key emerging devices in the commercial silicon-solar-cell sector. It is essential to have a suitable bottom cell in perovskite/silicon tandem solar cells for commercial use, given that good candidates boost efficiency through increased voltage. This is due to low recombination loss through the use of polysilicon and tunneling oxides. Here, a thin amorphous silicon layer is proposed to reduce parasitic absorption in the near-infrared region (NIR) in TOPCon solar cells, when used as the bottom cell of a tandem solar-cell system. Lifetime measurements and optical microscopy (OM) revealed that modifying both the timing and temperature of the annealing step to crystalize amorphous silicon to polysilicon can improve solar cell performance. For tandem cell applications, absorption in the NIR was compared using a semitransparent perovskite cell as a filter. Taken together, we confirmed the positive results of thin poly-Si, and expect that this will improve the application of perovskite/silicon tandem solar cells.
