By in-situ polymerization of 3,4-ethylenedioxythiophene monomers on the surface of graphene oxide, a PEDOT-GO film is formed as a hole transport layer (HTL) to lower the cost and avoid corrosion of the perovskite and the use of solvent. The highest power conversion efficiency (PCE) achieved is 14.09%.
It is important to lower the cost and stability of the organic-inorganic hybrid perovskite solar cells (PSCs) for industrial application. The commonly used hole transport materials (HTMs) such as Spiro-OMeTAD, poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) and poly(3-hexylthiophene-2,5-diyl) (P3HT) are very expensive. Here, 3,4-ethylenedioxythiophene (EDOT) monomers are in-situ polymerized on the surface of graphene oxide (GO) as PEDOT-GO film. Compared to frequently used polystyrene sulfonic acid (PSS), GO avoids the corrosion of the perovskite and the use of H2O solvent. The composite PEDOT-GO film is between carbon pair electrode and perovskite layer as hole transport layer (HTL). The highest power conversion efficiency (PCE) is 14.09%.
