The molecular structure of the PEDOT chains in modified PEDOT: PSS can be manipulated. The contact angle of HTMs influences the grain size in CH3NH3PbI3 thin films. The surface roughness of HTMs influences the grain size in CH3NH3PbI3 thin films. The PCE of CH3NH3PbI3 based solar cells was improved from 11.6% to 13.0%.
