Electrohydrodynamic atomization (EHDA) or electrospraying stands out in thin film deposition because of its unique ability to form charged droplets, initiating higher deposition efficiencies in electrostatic spray deposition. Considering that the quality of a thin film depends on the particle sizes, their monodispersity and uniform distribution on the surface, electrospray is a powerful tool in materials synthesis. Therefore, this review looks at different areas where this novel technique has been used to improve on the overall performance of materials for energy devices, such as solar cells, photoelectrochemical cells, rechargeable batteries and beyond, capacitors, and (O)LEDs, including quantum dots.
