All-Inorganic Hydrothermally Processed Semitransparent Sb₂S₃ Solar Cells with CuSCN as the Hole Transport Layer.

ABSTRACT: An inorganic wide-bandgap hole transport layer (HTL), copper(I) thiocyanate (CuSCN), is employed in inorganic planar hydrothermally deposited Sb₂S₃ solar cells. With excellent hole transport properties and uniform compact morphology, the solution-processed CuSCN layer suppresses the leakage current and improves charge selectivity in an n-i-p-type solar cell structure. The device without the HTL (FTO/CdS/Sb₂S₃/Au) delivers a modest power conversion efficiency (PCE) of 1.54%, which increases to 2.46% with the introduction of CuSCN (FTO/CdS/Sb₂S₃/CuSCN/Au). This PCE is a significant improvement compared with the previous reports of planar Sb₂S₃ solar cells employing CuSCN. CuSCN is therefore a promising al
