Silicon nanowire/organic hybrid solar cells with zonyl fluorosurfactanct treated PEDOT:PSS

In this work, we added Zonyl fluorosurfactant into poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) to improve the affinity of PEDOT:PSS and silicon nanowire (SiNW) arrays. The concentration of Zonyl fluorosurfactant is 0%, 0.1%, 0.5%, 1%, and 10%. The 0.5%-Zonyl treated PEDOT:PSS/SiNW solar cell has the highest open-circuit voltage of 0.541 V, but the best efficiency is the device with 0.1%-Zonyl treated PEDOT:PSS. The efficiency is 9.18%.
