Two-Dimensional Transition Metal Oxides (TMOs) for Solar Cell Applications

Recent research has shown that two-dimensional transition metal oxides (TMOs) are potential materials for improving the stability and efficiency of solar cells. The brief overview of TMOs’ potential for use in solar cell applications in this abstract emphasizes their special qualities, synthesis techniques, and most recent developments. Due to their various chemical compositions and electrical structures, transition metal oxides have been thoroughly researched for their potential in renewable energy technologies, particularly in photovoltaics. Due to their fascinating electrical characteristics and simplicity of integration into solar cell topologies, two-dimensional TMOs like vanadium pentoxide (V2O5), tungsten diselenide (WSe2), TiO2 (titanium dioxide), zinc oxide (ZnO), tin dioxide (SnO2) has drawn a lot of attention. TMOs’ distinctive electrical band structures make effective charge separation and light absorption possible, both of which are essential for the performance of solar cells. TMOs have variable bandgaps that enable them to absorb various sun-spectrum wavelengths. TMOs are a good choice for single-junction and tandem solar cells because of their superior charge transfer capabilities and tunability. TMOs’ adaptability in terms of synthesis techniques is one of their main benefits. High-quality TMO thin films have been created using various methods, including chemical vapor deposition (CVD), liquid-phase exfoliation, and atomic layer deposition (ALD). These techniques enable the optimization of TMO features for particular solar cell applications by providing fine control over thickness, shape, and composition. The development of TMO-based solar cells has been impressive recently. Particularly, tandem solar cells profit from the superior optical qualities of TMOs. Researchers have significantly increased power conversion efficiency by mixing TMOs with other semiconducting substances like silicon or perovskites. TMOs have been included in many solar cell topologies, such as thin-film, organic, and quantum dot solar cells, proving their versatility. The long-term survival of solar cell technologies depends on TMOs’ exceptional stability and durability in adverse environmental conditions. They are desirable options for outdoor applications and have longer operational lifetimes because of their resistance to corrosion and photo-induced degradation.
