Colloidal Sb₂S₃nanocrystals: synthesis, characterization and fabrication of solid-state semiconductor sensitized solar cells

Abstract

Antimony sulfide nanocrystals of various shapes and different phases are synthesized using a colloidal hot-injection method, and the as-prepared nanocrystals are used as a light harvesting material in photovoltaic devices.

Sb2S3 Solar Cells

“…95 A device with a ZnO-nw/TiO 2 /Sb 2 S 3 / P3HT/Au structure demonstrated 2.3% PCE and V OC of 656 mV under optimized conditions. There were more attempts to modify SSC fabrication stages, such as to use Sb 2 S 3 quantum dots, [96][97][98] pre-formed HTL, 99 and alternative electron transport materials, 100,101 but their performance was significantly lower than that of the SSC device with conventional architecture.…”

Review of Recent Progress in Antimony Chalcogenide‐Based Solar Cells: Materials and Devices

“…The properties of antimony chalcogenides are determined predominantly by their components, crystal structures, sizes, and morphologies . Therefore, the synthesis of antimony chalcogenide materials with well‐controlled components, sizes, and shapes is of great significance for their application.…”

“…Metal‐organic precursor solutions can be prepared by dissolving metal oxides, metal hydroxides, metal chlorides, metal acetates, and metal acetylacetonates in thioglycolic acid and ethanolamine . Abulikemu et al reported a hot‐injection method to fabricate Sb 2 S 3 nanocrystals using antimony chloride as a source of Sb, bis(trimethylsilyl) sulfide as a source of S and oleic acid and 1‐octadecene as solvents. The nanocrystals obtained can be redispersed in toluene for spin‐casting deposition of Sb 2 S 3 films.…”

Synthesis of Bi2−2xSb2xS3 (0 ≤ x ≤ 1) solid solutions from solventless thermolysis of metal xanthate precursors

“…19,20 These contrasts in the molar ratios of Bi/(Sb+Bi) have been ascribed to the operation of so-called semi-metal boiling, during which a sudden alteration in the Sb 2 S 3 /Bi 2 S 3 (Sb/Bi) ratio arises at a specific point along the flow path due to preferential volatilisation and loss of antimony from the ore fluid. [20][21][22] Numerous approaches have been employed for the preparation of Sb 2 S 3 and Bi 2 S 3 nanoparticles and thin films including solvothermal, 23,24 hydrothermal, 25,26 single-source routes, [27][28][29][30] colloidal methods; 16,31,32 melt thermolysis, 33 dip-dry techniques, 34 chemical bath deposition, 35,36 aerosol-assisted chemical vapour deposition (AA-CVD), 37 spray pyrolysis, 38,39 and successive ionic layer adsorption reactions (SILAR) have also been used. 40,41 Solventless thermolysis has advantages over other routes, as it is a simple method in which solid state decomposition of a precursor is achieved by thermal treatment under inert conditions.…”
