“…Soon, better performances were obtained in the planar structure, where NiO hole selective layers (HSL) can be deposited using a vast range of techniques: sputtering, atomic layer deposition (ALD), e‐beam deposition, and NiO nanoparticles casting . The sol‐gel spin coating route is particularly appealing because of its low cost and because it offers the possibility to implement doping, by, e.g., copper, easily. Other doping elements, such as Li, Ag, Co, Zn, and Cs have also been successfully introduced into NiO, resulting in improved conductivity.…”

The effect of sodium doping in NiO as a contact layer for perovskite solar cells is investigated. A combined X‐ray diffraction and X‐ray photoelectron spectroscopy analysis reveals that Na+ mostly segregates as NaOx/NaCl species around NiO crystallites, with the effect of reducing interface capacitance as revealed by impedance spectroscopy. Inspired by this finding, the NiO/perovskite interface in perovskite solar cells is modified via insertion of an ultrathin NaCl interlayer, which increases the NiO work‐function by 0.3 eV. This leads to an increase of power conversion efficiency, approaching 18%, and open‐circuit voltage due to a remarkable suppression of surface recombination, as revealed by photoluminescence analysis and light intensity–dependent electrical measurements.

“…Different HTLs obtained depositing CuI on the top of NiO have been fabricated considering several concentrations of CuI (0.05 M; 0.10 M; 0.20 M) in acetonitrile. Both NiO [41] and CuI were deposited via spin coating (see the experimental section and the device architecture presented in Figure 1). Scanning electron microscopy (SEM) images of CuI film on NiO are reported in Figure 2 (from a to d).…”

“…The photoluminescence (PL) emission peak for the MAPbI 3 film (used as a reference on glass) and for HTL/ MAPbI 3 is shown in Figure 3b for the different single and double HTLs. By introducing the HTL, the MAPbI 3 PL emission is quenched [41] with respect to pristine MAPbI 3 . This effect is more pronounced in the presence of NiO/CuI HTL with comparison to single NiO HTL.…”

Copper Iodide Interlayer for Improved Charge Extraction and Stability of Inverted Perovskite Solar Cells

Nickel oxide (NiO) is one of the most promising and high-performing Hole Transporting Layer (HTL) in inverted perovskite solar cells due to ideal band alignment with perovskite absorber, wide band gap, and high mobility of charges. At the same time, however, NiO does not provide good contact and trap-free junction for hole collection. In this paper, we examine this problem by developing a double hole transport configuration with a copper iodide (CuI) interlayer for efficient surface passivation. Transient photo-current (TPC) measurements showed that Perovskite/HTL interface with CuI interlayer has an improved hole injection; CuI passivation reduces the concentration of traps and the parasitic charge accumulation that limits the flow of charges. Moreover, we found that CuI protect the HTL/perovskite interface from degradation and consequently improve the stability of the cell. The presence of CuI interlayer induces an improvement of open-circuit voltage VOC (from 1.02 V to 1.07 V), an increase of the shunt resistance RSH (100%), a reduction of the series resistance RS (−30%), and finally a +10% improvement of the solar cell efficiency.
