“…Tablero et al calculated the energy levels of several different impurities at substitutional sites in CIS, which was the first step toward identifying potential candidates for intermediate band formation in this material . In a subsequent work, it was also demonstrated that bismuth and oxygen orbital combinations created an intermediate band in oxygen-doped Cu 3 BiS 3 . The incorporation of V, Cr, and Ir by substitution at cation sites in CZTS was also studied, and it was demonstrated that these elements were able to introduce full, empty, and partially full intermediate bands depending on the substitutions .…”

This review captures the synthesis, assembly, properties, and applications of copper chalcogenide NCs, which have achieved significant research interest in the last decade due to their compositional and structural versatility. The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

“…1) of the Cu 3 BiS 3 compound has been determined as orthorhombic (P2 1 2 1 2 1 : space group no. 19) with a = 7.723 Å , b = 10.395 Å , and c = 6.716 Å [8]. The density of the synthesized Cu 3 BiS 3 is 6.01 9 10 3 kg/m 3 and calculated mass density is 6.11 9 10 3 kg/m 3 , the same as that of an ideal cell dimension with 4 (Cu 3 BiS 3 ) per cell [9].…”

“…This inherent efficiency, coupled with tunable band gaps, useful electrical properties, makes Cu 3 -V-VI family materials attractive as potential candidates for investigation and development of new singlejunction solar cell. Later on, Tablero [8] studied the electronic properties of Cu 3 BiS 3 by using first-principles density functional method. He had reported maximum efficiency obtained for Cu 3 BiS 3 :O with the results of generalized gradient approximation (GGA) and local density approximation (LDA) first-principles calculations was 50%.…”

Since the last few decades, light-absorbing materials based on CuInGaSe 2 (CIGS), CuInS 2 (CIS), and CdTe have dominated the research in thin-film solar cells.To fabricate large-scale solar cells from these materials, problems may arise due to limited availability of the constituents, viz. Se, In, Cd, and Te, and the toxicity of some of these elements. Hence, recent research efforts are attentive toward abundantly available non-toxic, larger value of absorption coefficient and non-conventional elements. The Cu 3 BiS 3 having wittichenite orthorhombic structure is one the most promising absorber layer candidates for low-cost thin-film solar cells. It has suitable direct band gap (1.10-1.86 eV), large absorption coefficient (10 5 cm -1 ) with composition of earth abundant, and relatively non-toxic and cost-effective constituents. Till now, a majority work was done on the preparation of Cu 3 BiS 3 thin films by various techniques. Therefore, a comprehensive review of recent literature of Cu 3 BiS 3 is urgently required. This paper will review the various techniques that have been used to deposit Cu 3 BiS 3 semiconductor with the hope of new paths for the beginner.

“…A study on defect states and surface passivation of p-type Cu 3 BiS 3 has recently been reported [11]. Theoretical studies suggest that doping Cu 3 BiS 3 with oxygen can be used for the formation of an intermediate band (IB) extending theoretical limit of conversion efficiency for Cu 3 BiS 3 -based IB solar cell to 46% [12]. There are no publications on experimental studies of the electronic band structure.…”

The elemental composition, structural and electronic properties are studied. The Raman spectrum shows four modes with the dominant peak at 292 cm −1 . Photoreflectance spectra demonstrate two band gaps E gX and E gY , associated with the X and Y valence sub-bands, and their evolution with temperature. Fitting the temperature dependencies of the band-gaps gives values of 1.24 and 1.53 eV for E gX and E gY at 0 K as well as the average phonon energy. Photoluminescence spectra at 5 K reveal two bright and broad emission bands at 0.84 and 0.99 eV, which quench with an activation energy of 40 meV. The photocurrent excitation measurements demonstrate a photoresponse and suggest a direct allowed nature of the band gap.
