“…Although these organic HTMs provide good carrier transport properties, which lead to high performance, high materials costs and unproven long-term stability are major impediments to industrial application. In contrast, inorganic HTMs, such as CuSCN, 124,125 CuI, 126 NiO, 127 and Cu∶NiO x , 107 are promising for more cost-effective and stable performance. The highest efficiency reported to date for an inorganic material was 17.7% with Cu∶NiO x as the HTM.…”

Energy 6(2), 022001 (2016), doi: 10.1117/1.JPE.6.022001. Abstract. Organo-metal halide perovskite-based solar cells have been the focus of intense research over the past five years, and power conversion efficiencies have rapidly been improved from 3.8 to >21%. This article reviews major advances in perovskite solar cells that have contributed to the recent efficiency enhancements, including the evolution of device architecture, the development of material deposition processes, and the advanced device engineering techniques aiming to improve control over morphology, crystallinity, composition, and the interface properties of the perovskite thin films. The challenges and future directions for perovskite solar cell research and development are also discussed.

“…The highest efficiency reported to date for an inorganic material was 17.7% with Cu∶NiO x as the HTM. 107 It should be noted that HTM-free and ETM-free designs have also attracted attention. The HTM is not a prerequisite for perovskite solar cells when a high-quality perovskite layer with benign interface properties is presented.…”

“…Ideal CTLs need to meet suitable energy levels for the injection of charges and efficient charge transport by blocking opposite charges 15, 16. The bottom CTL also influences the growth of the perovskite crystal and its quality of interface,17, 18, 19, 20, 21 which is very important for the performance of PeLEDs.…”

Control of Interface Defects for Efficient and Stable Quasi‐2D Perovskite Light‐Emitting Diodes Using Nickel Oxide Hole Injection Layer

Metal halide perovskites (MHPs) have emerged as promising materials for light‐emitting diodes owing to their narrow emission spectrum and wide range of color tunability. However, the low exciton binding energy in MHPs leads to a competition between the trap‐mediated nonradiative recombination and the bimolecular radiative recombination. Here, efficient and stable green emissive perovskite light‐emitting diodes (PeLEDs) with an external quantum efficiency of 14.6% are demonstrated through compositional, dimensional, and interfacial modulations of MHPs. The interfacial energetics and optoelectronic properties of the perovskite layer grown on a nickel oxide (NiOx) and poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate hole injection interfaces are investigated. The better interface formed between the NiOx/perovskite layers in terms of lower density of traps/defects, as well as more balanced charge carriers in the perovskite layer leading to high recombination yield of carriers are the main reasons for significantly improved device efficiency, photostability of perovskite, and operational stability of PeLEDs.

Organic-inorganic hybrid halide perovskite materials have been a suitable active layer in solar cells due to the extraordinary photonic and electronic properties. Perovskite solar cells (PSCs), no matter conventional structure or inverted structure, contain several key interfaces, including electrode/electron transport materials (ETM) interface, ETM/perovskite interface, perovskite/hole transport materials (HTM) interface, HTM/electrode interface. The interface is vital to the overall performance of the devices, since the exciton formation, dissociation, and recombination are directly related to the interface. Moreover, the degradation of devices is also highly sensitive to the interface. As a result, the deep understanding of the interfacial charge transfer and corresponding interfacial engineering is extremely important to achieve high-performance and high-stability PSCs. This review mainly focuses on the recent progress of interfacial engineering in PSCs, including conventional structured PSCs, PSCs employing carbon counter electrode, and inverted structured PSCs.
