V<sub>2</sub>O<sub>5</sub> thin films for energy storage and conversion

V₂O₅ is one of the best material for many applications. Progress is currently made to improve its performance for use as a sensor, or an electrode, or smart window, electrochromic device, supercapacitor, photovoltaic applications among others. In this work, we review the progress that has been done these recent years, in relation to the mode of preparation of the V₂O₅ films. The results outline the complex relationship between the synthesis and the properties, which should serve as a guide for further research on the dependence of the best synthesis process on the type of application that is targeted.
