Versatile fabrication of a passivation material, solute PEDOT:PSS, for a c-Si substrate using alcoholic solvents

Abstract

A different aspect of PEDOT:PSS as a passivation material of c-Si known as solute PEDOT:PSS is reported, where the carrier lifetimes of passivated c-Si are recorded to be more than 1 millisecond under an injection level of 1 × 10¹⁴ cm⁻³. Optimizing its fabrication with different solvents opens a universal route to produce excellent passivation materials which are facile, reproducible, and environmentally friendly.
