Abstract

We present the growth of In 2 S 3 onto Cu 3 BiS 3 layers and soda-lime glass (SLG) substrates by using chemical bath deposition (CBD) and physical co-evaporation. The results reveal that the microstructure and the optical properties of the In 2 S 3 films are highly dependent on the growth method. X-ray diffractrograms show that In 2 S 3 films have a higher crystallinity when growing by co-evaporation than by CBD. In 2 S 3 thin films grown by CBD with a thickness below 170 nm have an amorphous structure however when increasing the thickness the films exhibit two diffraction peaks associated to the (1 0 3) and (1 0 7) planes of the β-In 2 S 3 tetragonal structure. It was also found that the In 2 S 3 films present an energy bandgap (E g ) of about 2.75 eV, regardless of the thickness of the samples.
