Hybrid solar cells from Sb2S3 nanoparticle ink

Abstract

Sb 2 S 3 is a promising candidate for solar cell absorbers due to its high absorption coefficient, suitable band gap and earth-abundant constituents. Here we present the preparation of hybrid solar cells from an ink of colloidal Sb 2 S 3 nanoparticles and P3HT. Colloidal Sb 2 S 3 nanoparticles were prepared via hot injection method. Solar cells based on these nanoparticles achieves a power conversion efficiency of 1.5%, which is efficiency record for planar hybrid solar cells based on Sb 2 S 3 nanoparticles. We investigated in detail the role of the capping agents on the performance of solar cells.

Uniform Sb2S3optical coatings by chemical spray method

“…Metastibnite-Sb 2 S 3 forms when formation of stibnite-Sb 2 S 3 is halted by insufficient reaction time and energy [44–46]. Volmer–Weber island growth of amorphous Sb 2 S 3 (and in some cases leaf-like grains of polycrystalline Sb 2 S 3 ) have been observed in Sb 2 S 3 layers grown by chemical bath deposition on glass [47–48], In 2 O 3 /Sn (ITO) [49], planar TiO 2 [16] and TiO 2 nanotube arrays [50], by sequential deposition [51] and spin coating [8,52] on planar TiO 2 , by photochemical deposition on mesoporous TiO 2 [53], by thermal evaporation on planar CdS [27] and planar TiO 2 [54]. Supported by these numerous observations, we consider the Volmer–Weber growth characteristic of Sb 2 S 3 , given that the substrate and deposition conditions are met.…”

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.…”

Modeling and analysis of optical properties of nanoparticles and nanofluids for effective absorption of solar radiation and their heating

“…The applications of NPs in various solar cells can be used for increasing cells efficiency and are discussed in [147][148][149][150][151][152][153][154][155][156]. General problems of the NPs use in solar cells are investigated [147][148][149][150][151][152] taking into account quantum-sized nanomaterials for solar cell applications [147], possible strategies and recent results in plasmonic enhanced solar cells [148], optimized TiO 2 NPs packing for photovoltaic applications [150], performance enhancement of photovoltaic cells by changing configuration and using Al 2 O 3 NPs [151] and influence of the Cu 2 ZnSnS 4 NPs size on solar cell performance [152].…”

“…Hybrid solar cells from Sb 2 S 3 NP ink [153], device performance enhancement of polymer solar cells by NP selfassembly [154], plasmonic effect of gold NPs in organic solar cells [155] and novel synergistic combination of Al/N Co-doped TiO 2 NPs for highly efficient dye-sensitized solar cells [156] were investigated and discussed.…”
