Temperature Solution

Here, a low-temperature solution-processed nickel oxide (NiOx) thin film was first employed as a hole transport layer in both inverted (p-i-n) planar and regular (n-i-p) mesoscopic organic–inorganic hybrid perovskite solar cells (PVSCs).

Formation Reaction

Abstract Nickel oxide (NiOx) hole transport layer was made from nickel oxide powder by a simple process and non-stabilizer or chelating agent. We used ethanol as main solvent and nitric acid less than 2% as co-solvent. The formation reaction mechanism of NiOx thin film was also studied. Perovskite solar cells (PSCs) with the optimum thickness of 70 nm exhibited power conversion efficiency as high as 12.99%, which is superior to those of PSCs with their counterparts. The moisture stability of NiOx based device (non-encapsulated) remained above 70% of their initial output after 700h storage at ambient conditions.

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%.

Interface Contact

A ferrocenedicarboxylic acid modified NiOx layer greatly improves the crystallization of a perovskite, its interface contact properties and electrical conductivity and also passivates the interface.
