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 (Sb_2S_3, Sb_2Se_3) 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.
