CsPbBr3 nanocrystal inks for printable light harvesting devices

Author affiliations

Abstract

The success of lead halide perovskites has grown thanks to their optimal optoelectronic properties. They also have potential for application in the processing of large area printed thin films and devices. Nevertheless, so far, there has been little understanding about the crystallization processes, which leads to a lack of control during the thin film formation. A promising approach is the synthesis of inks based on colloidal nanocrystals (NCs). Here we synthesized CsPbBr3 nanocrystal (NC) inks and we explored a number of parameters of the synthetic procedure in order to control the ink properties such as the NC size, shape and dispersion. This allowed us to deposit high quality thin films and we eventually demonstrate the fabrication of a 1 cm2 printed photovoltaic device.
