Regioregularity of P3HT is known to be one of the key parameters affecting the related solar cells performance, and critically depend on the regioselectivity of the synthetic approaches to conducting P3HT.
Intensive studies have also revealed that the regioregular polymerization of P3HT proceeds via a chain-growth mechanism and may also exhibit living characteristics.
This feature allows for the precise control of the polymer molecular weight and polydispersity, which were found to be, in turn, critical parameters modulating polymer electronic, optical, electrochemical properties, and solid-state packing, therefore influencing the OPV device performance
