The Cost

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%.

The Impact

Organic-inorganic hybrid perovskite solar cells (PSCs) has attracted growing attention in recent years due to its outstanding photovoltaic performance. After extensive studies in material designs and device engineering, the efficiencies of PSCs have been improved to 24.2%. On the other hand, the inadequate stability of PSCs is hindering the application to real life. Starting with the stability of organic-inorganic PSCs, this article analyzed and concluded the impact of doping A-site and X-site ions on the stability of perovskite respectively. Next, it put forward the prospects for possible development directions of this field in the future.
