“…Transition metal oxides have emerged as promising materials for these types of layers for different types of cells including silicon-based ones [2,152]. With a wide band gap, high optical transparency, and high work function (5.1-6.9 eV) [153][154][155], molybdenum oxides are one of the most outstanding candidates, whose interface with Si results in a very large hole barrier. An example is the theoretical studies carried out by Khokhar et al [156] where they simulate the effect of the MoO x work (J) MoO 3−x hybridized hyaluronic acid hollow nanospheres [142] (Reproduced from [143], with permission from Springer Nature).…”

The family of molybdenum oxides has numerous advantages that make them strong candidates for high-value research and various commercial applications. The variation of their multiple oxidation states allows their existence in a wide range of compositions and morphologies that converts them into highly versatile and tunable materials for incorporation into energy, electronics, optical, and biological systems. In this review, a survey is presented of the most general properties of molybdenum oxides including the crystalline structures and the physical properties, with emphasis on present issues and challenging scientific and technological aspects. A section is devoted to the thermodynamical properties and the most common preparation techniques. Then, recent applications are described, including photodetectors, thermoelectric devices, solar cells, photo-thermal therapies, gas sensors, and energy storage.

Ag/ITO/MoO x /n-Si/LiF x /Al carrier-selective contact (CSC) solar cell structures are modelled and numerically simulated based on the experimental data using an industrial quality base silicon wafer by the Sentaurus TCAD software. The role of (1) electron-selective lithium uoride (LiF x ) layer and its thickness, ( 2) hole-selective molybdenum oxide (MoO x ) work function variation, and (3) front contact (MoO x /n-Si) surface passivation interlayer are explored on the device performance. The electron-selective LiF x layer at the rear side is led to the strong enhancement in device photocurrent by providing the electrical barrier to the minority carriers (holes) and slight improvement in open-circuit voltage, but the thickness of the layer is sensitive to e cient extraction of the majority carriers (electrons). The holeselective MoO x layer work function needs to engineer for inducing the strong inversion layer with better built-in potential at the MoO x /n-Si junction to achieve high open-circuit voltage from a cell. A thin SiO x interlayer at the MoO x /n-Si junction has enhanced the device open-circuit voltage signi cantly by minimizing the minority carrier recombination at the interface.
