| 英文摘要 | A systematic study of the formation of the tunnel-junction for perovskite/TOPCon tandem solar cells is presented, which consists of a B-doped poly-Si (p(+)-poly-Si) and P-doped poly-Si (n(+)-poly-Si) double-layer structure. The rear emitter double-side TOPCon solar cell is selected as the bottom cell in tandem solar cells, where a p(+)-poly-Si/SiOx forms the rear emitter and an n(+)-poly-Si/SiOx forms the front field with the poly-Si layer deposited by plasma-enhanced vapor deposition (PECVD) and crystallized in a furnace. The tunnel-junction is formed by depositing an additional B-doped a-Si:H (p(+)-a-Si:H) on the front n(+)-poly-Si and following a rapid thermal anneal (RTA) to partially crystallize the p(+)-a-Si:H with minimized interdiffusion of B and P. The tunnel-junction is systematically optimized and it is found that the RTA process at 700 degrees C produces the optimized tunnel-junction with the minimal contact resistivity of approximate to 16 m omega cm(2). The tunnel-junction formation affects the passivation of the front field TOPCon, but the losses in the passivation quality can be recovered by a forming gas annealing. This process provides a simple and useful method for making the tunnel-junction in perovskite/TOPCon tandem solar cells. |
