A Review of the Impact of Zinc Oxide Nanostructure Morphology on Perovskite Solar Cell Performance

Zinc oxide (ZnO) has been widely studied over the last decade for its remarkable properties in optoelectronic and photovoltaic devices because of high electron mobility excitonic properties. It probably broadest range nanostructured forms that are also easy cheap to synthesize using a wide variety methods. The volume recent work on ZnO nanostructures their can potentially overshadow significant developments field. Therefore, there is need concise description most advances In this review, we focus effect nanostructure morphologies performance ZnO-based solar cells sensitized methylammonium lead iodide perovskite. We present an exhaustive discussion synthesis routes different nanostructure, ways controlling morphology, impact morphology photoconversion efficiency given perovskite cell (PSC). find although empirically similar, one-dimensional structures appear offer promise increasing (PCE) by proclivity align form vertically stacked layers. This thought favor hopping, charge mobility, conductivity allowing multiple conduction pathways effective junction cross-sectional area. combined net increase PCE due reduced surface reflection, improved light absorption.
