Abstract:This study proposes a titanium silicide (TiSi2) recombination
layer for perovskite/tunnel oxide passivated contact (TOPCon) 2-T
tandem solar cells as an alternative to conventional transparent conductive
oxide (TCO)-based recombination layers. TiSi2 was formed
while TiO2 was made by oxidizing a Ti film deposited on
the p+-Si layer. The reaction formation mechanism was proposed
based on the diffusion theory supported by experimental results. The
optical and electrical properties of the TiSi2 layer were
