I am doing Benzoquinone passivation for carrier selective solar. How to identify root case to S-shaped curves in these heterojunction solar cells?

I am doing benzoquinone(wide bandgap) passivation (thickness- a monolayer) for n-type silicon followed by spin coating PEDOT:PSS for my carrier selective solar cells and observing S-shaped curves...
