Evidence for Self-healing Benign Grain Boundaries and a Highly Defective Sb2Se3–CdS Interfacial Layer in Sb2Se3 Thin-Film Photovoltaics

The crystal structure of Sb2Se3 gives rise to unique properties that cannot otherwise be
achieved with conventional thin-film photovoltaic materials, such as CdTe or Cu (In, Ga)
Se2. It has previously been proposed that grain boundaries can be made benign provided
only the weak van der Waals forces between the (Sb4Se6) n ribbons are disrupted. Here, it
is shown that non-radiative recombination is suppressed even for grain boundaries cutting
across the (Sb4Se6) n ribbons. This is due to a remarkable self-healing process, whereby …
