Abstract

Perovskite solar cells (PSCs) have attracted great interest for rapidly growing light-to-electricity conversion efficiencies, already exceeding 22%, although they still lack high stability, especially in air and humidity. In this project, novel solution-processed oxide semiconductor materials will be prepared and characterized towards applications as hole- and/or electron-transport layers (HTL and ETL, respectively) in PSCs with enhanced efficiencies and stability.p-type (NiO, MoO3, V2O5 and/or graphene oxide) and n-type (TiO2 and/or ZnO) oxide semiconductors with desired band energies will be prepared via solution-processed methods. These materials will be deposited as thin films via solution-processed techniques, in special layer-by-layer (LbL) structures, with optimal electric, optical and morphological characteristics for applications as HTLs and/or ETLs in optoelectronic devices. PSCs will be fabricated in two different configurations employing a vacuum-assisted deposition of the active perovskite layer and the developed solution-processed HTLs and/or ETLs. The behavior and stability of the PSCs having the developed transport thin layers will be evaluated to elucidate the charge extraction effectiveness of the novel compact films. (AU)
