To replace the current transparent conductive oxides prepared from cost-intensive processes, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid)(PEDOT:PSS, PH1000) has been studied over the years due to its high electrical conductivity. Even though there have been some reports utilizing PEDOT:PSS as electrodes for perovskite solar cells, devices with n-i-p configuration and planar structure have not been investigated using PEDOT:PSS as the bottom electrode. MXene, a new class of two-dimensional transition metal carbides, shows promising characteristics of excellent metallic conductivity and hydrophilic surface properties, as well as n-type carrier properties. In this work, we tried to use a PEDOT:PSS/Ti3C2Tx composite layer to effectively transport electrons that were extracted into the tin oxide layer of planar perovskite solar cells. The electron transporting capabilities of the PEDOT:PSS/Ti3C2Tx composite layer was demonstrated using photoluminescence spectrum analysis. |
