Description
Summary:•3D branched CIS NWs has successfully synthesized by one-pot SLS process.•Branched CIS NWs are well demonstrated by TEM, XRD, HR-TEM and EDX etc.•Branched CIS as the light-absorbing layer in PVs have an attractive PCE of 0.361%. Branched CuInSe2 nanowires (NWs) are successfully synthesized by one-pot method for making secondary bismuth nanoparticles to attach onto the CuInSe2 NWs stem for inducing the secondary branch growth by solution-liquid-solid (SLS). The branched CuInSe2 NWs were measured in order to reveal its viability for PV device fabrication and application for the light-absorbing material in solar cells.
