Routes to increase performance for antimony selenide solar cells using inorganic hole transport layers.

ABSTRACT: Simple compound antimony selenide (Sb₂Se₃) is a promising emergent light absorber for photovoltaic applications benefiting from its outstanding photoelectric properties. Antimony selenide thin film solar cells however, are limited by low open circuit voltage due to carrier recombination at the metallic back contact interface. In this work, solar cell capacitance simulator (SCAPS) is used to interpret the effect of hole transport layers (HTL), i.e., transition metal oxides NiO and MoO _x thin films on Sb₂Se₃ device characteristics. This reveals the critical role of NiO and MoO _x in altering the energy band alignment and increasing device performance by the introduction of a high energy barrier to electrons at the
