Perovskite Solar Cells: Understanding the Doping Effect on NiO: Toward High‐Performance Inverted Perovskite Solar Cells (Adv. Energy Mater. 19/2018)

Abstract

In article number 1703519, Aleksandra B. Djuri?i?, Zhu-Bing He and co-workers synthesize Cu doped NiO nanoparticle ink that enables room temperature preparation of uniform, high quality hole transport layers. Increased work function and conductivity due to Cu doping result in improved charge extraction and reduced recombination losses, leading to high performance devices with power conversion efficiencies exceeding 20% on rigid and 17% on flexible substrates.
