Description

Description Bi2S3 is a semiconductor. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers.

Features And Benefits

Features And Benefits Bi2S3 belongs to the group-15 post-transition metal trichalcogenides.

Application

Application Bismuth sulfide has a good bandgap of 1.3 eV and a relatively large absorption coefficient in the near infrared, and can be used in solution-processed thermoelectric devices, photodetectors, photosensitizers, solar cells, and supercapacitors. Bi 2 S 3 is also an interesting candidate for polymer-nanoparticle hybrid solar cells.
