Effect of copper phthalocyanine (CuPc) as hole transport layer in perovskite solar cells

Abstract

Organic-inorganic hybrid perovskite photovoltaics are gaining a great attention because of their wide range of applications, while the selection of energy level suitable, high conductivity and commercial hole transport layers is still challenging. Here we familiarize thermally evaporated pristine copper phthalocyanine (CuPc) as hole transport layer in regular perovskite solar cells and validate improved photovoltaic performance, increased stability and uniformity compared to the device without CuPc layer. Here we attempt to develop a scheme for fabricating cost-effective and flexible perovskite solar cells without using a glove box set up.
