Efficient Se‐Rich Sb2Se3/CdS Planar Heterojunction Solar Cells by Sequential Processing: Control and Influence of Se Content

Sb2Se3 Absorbers In article number 2000141, Pedro Vidal-Fuentes, Edgardo Saucedo, and co-workers find the annealing temperature to be the main parameter controlling the composition of the Se-rich quasi-one-dimensional Sb2Se3 absorbers for solar cell applications, synthesized by a sequential process using thermal evaporation of Sb, followed by reactive annealing under Se atmosphere. As a consequence, the optoelectronic parameters of the solar cells strongly depend on the Se excess.
