In this presentation, I will introduce on-going research to apply the nanoscale oxide layers to perovskite solar cells (PSCs) as the carrier transport layer or the conducting transparent oxide layer. The first part of the presentation will be focused on flexible solar cells using inorganic-organic halide perovskite light absorber. Our results show that the thermally oxidized Ni film can be an excellent hole transport layer of PSCs and the residual stress in NiO film is an important parameter to control the carrier recombination of PSCs. In the second part, a design rule of multi-functional transparent electrode for stable and efficient PSCs will be presented. By combining experimental and theoretical methods, we have explored transparent and conducting dielectric/metal/dielectric multilayers. This multilayer is not only a good transparent electrode but also a good passivation layer to suppress the photodegradation of PSCs.
