Perspectives on the merits of cubic Silver Antimony Sulfide-Selenide thin films for Solar Cells

Symposium: C7 Photovoltaics, Solar Energy Materials and Technologies
Authors: J. Capistrán-Martínez, M.T.S. Nair, P.K. Nair
Congress participation: Virtual

  • The silver antimony sulfide-selenide – cubic-AgSb(S,Se)2 is a potential p-type semiconductor for application in thin-film solar cells. In this work, we present perspectives of AgSb(S,Se)_2 to develop high-efficiency solar cells using this cubic metal chalcogenide.

  • The merit of incorporating silver atoms into the novel antimony chalcogenides (Sb2S3, Sb2Se3) comes from the transformation of orthorhombic structure into an FCC lattice, similar to that in rock salt structure.

  • At this stage, chemical deposition has served for prototyping the solar cells. Improvements are expected using industrial chalcogenide growth techniques, which would enhance their carrier collection.
