“…The copper based chalcogenide thin films including Cu2ZnSnSSe4 (CZTSSe, kesterite), CuSbS2 (chalcostibite) and Cu3BiS3 (Wittichenite) comprise abundant, low cost and non-toxic elements with a p-type conductivity, and are extensively investigated as an absorber layer for solar cells. These materials are also under extensive research due to their environmentfriendly response and appropriate characteristics to harvest the solar energy [2][3][4][5][6][7]. Colombara et al studied thermochemical and kinetic aspects of the CuSbS2 and Cu3BiS3 produced by the conversion of the stacked and co-electroplated metal precursors in the presence of sulfur vapors [8].…”

Copper antimony sulphide (Cu3SbS3) with a p-type conductivity and optical band gaps in the range of 1.38 to 1.84 eV is considered to be a promising solar harvesting material with non-toxic and economical elements. In this study, we reported the fabrication of Cu3SbS3 thin films using successive thermal evaporation of Cu2S and Sb2S3 layers followed by annealing in an argon atmosphere at a temperature range of 300-375°C. The structural and optical properties of the asdeposited and annealed films were investigated. The annealed films notably show the crystalline phase of the Cu3SbS3, identified from the X-ray diffraction analysis and endorsed by the Raman analysis as well. Whereas their chemical state of the constituent elements was characterized with X-ray photoelectron spectroscopy. The measured highest resistivity of the annealed film was found to be ~0.2 Ω-cm. Hence, our obtained results for the fabricated Cu3SbS3 thin films bring to light that Cu3SbS3would be a good absorber layer in solar cells due to their low resistivity, a higher value of the optical absorption coefficient (~10 5 cm -1 ), the low transmittance (<5%) and an optical direct band gap of 1.6 eV in the visible range of the solar spectrum.

“…1 Introduction Cu 2 ZnSnS 4 (CZTS) is one of the hopeful materials for the next generation of solar cells due to its non-toxic and earth-abundant constituents, direct band gap energy (~1.5 eV) and large absorption coefficient (>10 4 cm -1 ) [1]. Several vacuum and non-vacuum based techniques have been reported for the synthesis of CZTS thin films such as sputtering, pulsed laser deposition, coevaporation, hydrothermal, electrodeposition, sol-gel, drop casting, etc.…”

Cu2ZnSnS4 (CZTS) is a promising thin film absorber material for low cost solar cell applications. Its absorption coefficient (∼ 104 cm‐1), crystal structure and band gap energies (∼1.5 eV) are similar to those of Cu(In,Ga)Se2 (CIGS), one of the most studied and flourishing thin film solar cell absorber materials. However, unlike CIGS, which requires the expensive and rare elements; In and Ga, CZTS is composed of reasonably priced and abundant elements like Zn and Sn. In the present investigation, kesterite CZTS nanoparticle inks were obtained by a hydrothermal process using Cu, Zn and Sn chlorides, and Na sulfide. The synthesized CZTS nanoparticles were characterized using optical absorption, X‐ray powder diffraction (XRD), energy dispersive spectroscopy (EDS), micro‐Raman spectroscopy, high‐resolution transmission electron microscopy (HRTEM), and X‐ray photoelectron spectroscopy (XPS). The optical and morphological properties demonstrated that the prepared nanoparticles have strong absorption in 300−550 nm range with band gap energy of 1.55 eV with an average particle size of 20 nm. The X‐ray and micro‐Raman analysis revealed that the synthesized CZTS nanoparticles have the phase pure kesterite structure. We believe that our synthetic method will be helpful for low‐cost and efficient thin film photovoltaic technology. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…Although a chemical method has shown higher power conversion efficiency (PCE) [4], physical methods avoid the toxicity of chemical methods [5]. Therefore, thin films can be prepared by various physical methods like pulsed laser deposition, thermal evaporation, atomic beam epitaxy, Direct Current (DC) and radio frequency sputtering [6][7][8][9][10].…”

In this study, we report Cu2ZnSn(S,Se)4 (CZTSSe) thin films synthesized by using a rapid thermal annealing process of direct current sputtered precursors under a sulfur and selenium atmosphere. X‐ray diffraction and Raman spectroscopy investigations showed formation of CZTSSe absorber layer without any secondary phase. X‐ray fluorescence spectroscopy showed a stoichiometric absorber layer has been formed which is suitable for use in solar cells. The best thin film solar cell of CZTSSe showed a photovoltaic performance of 5.2% efficiency (Voc: 585.0 mV, Jsc: 17.0 mA/cm2 and FF: 52.0%). This is the highest efficiency reported for CZTSSe prepared from sputtered Cu/Zn/Sn precursors followed by sulfo‐selenization using powder sources. (© 2015 WILEY‐VCH Verlag GmbH & Co.
