Efficient and stable all-inorganic Sb2 (S, Se) 3 solar cells via manipulating energy levels in MnS hole transporting layers
The use of organic hole transport layer (HTL) Spiro-OMeTAD in various solar cells imposes
serious stability and cost problems, and thus calls for inorganic substitute materials. In this
work, a novel inorganic MnS film prepared by thermal evaporation has been demonstrated
to serve as a decent HTL in high-performance Sb 2 (S, Se) 3 solar cells, providing a cost-
effective all-inorganic solution. A low-temperature air-annealing process for the evaporated
MnS layer was found to result in a significant positive effect on the power conversion …
