Abstract: Recently, organic/inorganic hybrid perovskite materials, APbX3 (A = CH3NH3 or HC(NH2)2; X = I, Br or Cl), have attracted much interest for their promising application in solar cells as the light-absorbing component to their broad spectral absorption, strong light-harvesting and long exciton diffusion length. The perovskite solar cells (PSCs) can reduce the production costs and achieve high power conversion efficiency significantly compared to standard silicon cells and other thin film cells. On the other hand, ZnO based materials have been recently investigated in the PSCs devices as electron injection layers for low-temperature, low-cost and flexible devices. This chapter aims to review PSCs using ZnO materials as electron extraction layers. We will discuss the electron transmission and effect of the electron-transporting layer in PSCs and the preparation method of the ZnO. ZnO is a potential material for many applications due to their high electron mobility, transparent and various nanostructure. The ZnO was introduced into the PSCs structure to improve electron extraction efficiency. This chapter summaries the effect and parameters of PSCs based on the ZnO layer/nanostructure prepared by several methods as electron transport layers.
