Cation Disorder and Local Structural Distortions in AgxBi1–xS2 Nanoparticles
(MDPI, 2020-02-12)
Article
Open AccessBy combining X-ray absorption fine structure and X-ray diffraction measurements with density functional and molecular dynamics simulations, we study the structure of a set of AgxBi1−xS2 nanoparticles, a materials system ... -
Cation disorder engineering yields AgBiS2 nanocrystals with enhanced optical absorption for efficient ultrathin solar cells
(Springer Nature, 2022-03)
Article
Open AccessStrong optical absorption by a semiconductor is a highly desirable property for many optoelectronic and photovoltaic applications. The optimal thickness of a semiconductor absorber is primarily determined by its absorption ... -

Colloidal AgBiS2 nanocrystals with reduced recombination yield 6.4% power conversion efficiency in solution-processed solar cells
(Elsevier, 2020-05-28)
Article
Open AccessAgBiS2 nanocrystals have recently emerged as a RoHS compliant material for photovoltaics. This heavy-metal-free ternary chalcogenide can be prepared from earth-abundant precursors, is solution-processable and presents a ... -
Mixed AgBiS2 nanocrystals for photovoltaics and photodetectors
(Royal Society of Chemistry, 2022-03-03)
Article
Open AccessHeavy-metal-free colloidal nanocrystals are gaining due attention as low-cost, semiconducting materials for solution-processed optoelectronic applications. One common limitation of such materials is their limited carrier ...
