MOS Electron Transport Layers as Solar Cells

Abstract

Ultrasonic spray pyrolysis technique emerges as the simplest and most feasible. For thin- film preparation, this method is superior to other techniques because it produces relatively homogeneous compositions, allows easy control of film thickness, and yields a fine and porous microstructure. The size of the nanoparticle prepared from various techniques is less 80 nm and it has spherical in shape in nature. In this review, reported methods for synthesizing potential ETL materials are summarized, and an attempt is made to guide further research in this field. With concerted efforts, the ultrasonic spray pyrolysis technique could serve as a change agent in synthesizing efficient materials for solar cell applications and thus significantly enhance their efficiency.
