Phosphine-free synthesis of heavy Co2+- and Fe2+-doped Cu2SnSe3nanocrystals by virtue of alkylthiol-assistant Se powder dissolution

Abstract

We demonstrate a phosphine-free method to synthesize heavy Co2+- and Fe2+-doped Cu2SnSe3 nanocrystals (NCs) by virtue of alkylthiol-assistant Se powder dissolution in organic solvents. The as-synthesized NCs exhibit a promising increase in photocurrent under AM1.5 illumination. Since the current method is simple and convenient it holds promise for facilitating the progress in photovoltaic devices from Cu-based NCs.
