Figure 8: (a) JV curve and (b) EQE curve of 2T perovskite/c-Si
tandem solar cell with poly-SiOx passivated c-Si bottom
cell. The corresponding device structure is shown in Figure 1. The blue,
red and black curves represent EQE spectra of perovskite top cell, c-Si
bottom cell and tandem cell respectively. The area covered by the blue
line indicates the photo-current density generated by the perovskite top
cell, while the area covered by the red line indicates the photo-current
density generated by c-Si bottom cell. |
