Structural, Optical, and Electrical Properties of Applied Amorphized and Polycrystalline Sb2S3 Thin Films

Abstract

One of the intermediate steps in the organo-colloidal synthesis of crystalline Sb 2 S 3 is a synthesis of spherical amorphous Sb 2 S 3 . In order to prove that the synthesized semiconductor can be considered an absorbing material for a solar device, the electronic and photovoltage properties of the amorphized and polycrystalline Sb 2 S 3 thin films deposited by synthesized amorphous nanoparticles were studied. Optical studies revealed that the direct band gap energy was 1.65 eV and, two direct allowed transition of 1.57 and 1.91 eV for polycrystalline and amorphized thin films, respectively. The PL spectra of Sb 2 S 3 showed an emission peak at 1.65 eV for both films.In order to obtain current-voltage (I-V) characteristics, two cells based on the Sb 2 S 3 thin films as both an absorbing material and an electrolyte were designed and made. The observed Sb 2 S 3 thin films, with a thickness of around 10 lm, are of p-type. The exponential growth of the I-V curves reveals that the cells can work as a generator of electricity.

The role of low light intensity: A cheap, stable, and solidly efficient amorphous Sb2S3 powder/hypericin composite/PVA matrix loaded with electrolyte solar cell

“…The optimum thickness yielding the highest efficiency and other cell parameters was found to be 100 nm. As given in our earlier paper synthesized amorphous Sb 2 S 3 film exhibit better photovoltaic performances than the crystalline Sb 2 S 3 one in photo‐electrochemical solar cell.…”

“…Independently of the performance of the tested solar cells under 1 sun, finding low‐cost cell technology combined with understanding of utilization of low light and setting of standard conditions (1–10 W m −2 , indoors) should be some future directions concerning the research in this area . Our opinion is backed up by experiments we carried out with synthesized Sb 2 S 3 solar cells operating at low light intensity, as well as the results presented in this article.…”

“…Also, the most intense planes in Figure A are indexed. It should be pointed out that there are no real differences in structures between the two samples (Sb 2 S 3 powder/hypericin composite thin film and Sb 2 S 3 thin film ) except in crystallinity and preferred plane orientations. It is obvious that the composite sulfide/dye film (Figure A) crystallized better than the sulfide film (Figure B).…”

“…Widely recognized semiconductor Sb 2 S 3 (as well as other metal sulfide semiconductors or a novel structure based on antimony sulfide) is one of the most promising materials for PV cells because of its high absorption coefficient, and therefore, it has been used in a number of cases to create solar cells As far as we are aware, only we have reported on the use of synthesized Sb 2 S 3 material in solar cell devices .…”

Fabrication of single crystal architecture in Sb-S-I glass: Transition from dot to line

“…Absorption spectroscopy revealed that the optical band-gap of the synthesized glasses and Sb 2 S 3 crystals is different with values 2.1 and 1.7 eV, respectively [17,18]. To cause absorption of the laser beam enough for heating of glasses but relatively small by crystal, we selected a CW diode laser with intermediate wavelength of 639 nm (i.e.…”
