Abstract

Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) is one of the most commonly used Hole Transporting Materials (HTMs) in a Perovskite Solar Cell (PSC). However, its low conductivity and local charge transport are issues that restrict the device’s performance. Moreover, PEDOT:PSS films have many pinholes and are inhomogeneous, leading to increased charge recombination. Thus, these significant drawbacks require an urgent address to enable PSCs to reach their desired efficiency values. In this paper, we have experimented by incorporating a washing technique using Isopropyl Alcohol (IPA). It was observed that the modified device improved the device efficiency to above 11%. The increase in device efficiency can be attributed to better conductivity, smoother charge transfer, superior film quality and improved material compatibility of different PSC components.
