Title: Influence of dipping cycles on physical, optical, and electrical properties of Cu 2 NiSnS 4 : Direct solution dip coating for photovoltaic applications

Abstract

Direct solution coating technique has emerged as a promising economically viable process for earth abundant chalcogenide absorber materials for photovoltaic applications. Here, direct ethanol based dip coating of earth abundant Cu2NiSnS4 (CNTS) films on soda lime glass (SLG), molybdenum coated glass (Mo), and fluorine doped tin oxide coated glass (FTO) substrates is investigated. The structural and morphological properties of pre-annealed and sulfurized CNTS films coated on SLG, FTO, and Mo substrates are reported. The influence of dipping cycles on composition and optoelectronic properties of pre-annealed and sulfurized CNTS films deposited on SLG substrate is presented. Energy dispersive spectroscopy (EDS) and X-ray fluorescence (XRF) analysis reveal how changes in thickness and elemental composition affect morphology and optoelectronic properties. The obtained absorption coefficient, optical bandgap, resistivity and mobility of pre - annealed and sulfurized films are found to be 104 cm-1, 1.5 eV, 0.48 Ocm, 3.4 cm2/Vs and 104 cm-1, 1.29 eV, 0.14 Ocm, 11.0 cm2/Vs, respectively. These properties are well suited for photovoltaic applications and lead to the conclusion that the direct ethanol based dip coating can be an alternative economically viable process for the fabrication of earth abundant CNTS absorber layers for thin film solar cells.

  • Antimony-doped tin dioxide possess interesting physical and chemical properties. These properties have a wide range of applications such as catalysis and optoelectronic devices. In the present study, antimony-doped tin oxide (SnO2:Sb) thin films were deposited on the quartz substrates by sol-gel dip coating technique. The films were annealed at temperatures 350°C, 550°C and 850°C in air for 2 hours. The structure and surface morphologies were observed by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). XRD patterns shows tetragonal structure for the SnO2:Sb films annealed at different temperatures. Crystallite size increased from 6 to 14 nm as annealing temperature increasedmore » from 350°C to 850°C. SEM studies reveals crack free and smooth surface for all the films. The grains are found to be homogenously distributed for films annealed at higher temperature. The electrical conductivity of the films annealed at 350°C and 550°C decreased and increased for the films annealed at 850°C. The optical properties of the films were investigated in the UV-visible-NIR region (200-900 nm) using UV spectra. The transmittance of the films decreased for films annealed at higher temperature. The optical energy band gap values (4.13 eV-4.83 eV) increased with the increase in annealing temperature.« less
  • Different compounds in the Cu{sub 2}ZnSnS{sub 4}–Cu{sub 2}ZnSiS{sub 4} system have been prepared via ceramic route and structurally characterized via X-ray diffraction on powders and single crystals. Two solid solutions were identified along the Cu{sub 2}Zn(Sn,Si)S{sub 4} series. Namely, materials with Si-content x=Si/(Sn+Si) lower than 0.5 crystallize with the Cu{sub 2}ZnSnS{sub 4} kesterite structure type while materials with x higher than 0.8 adopt the Cu{sub 2}ZnSiS{sub 4} enargite structure type. In between, a miscibility gap occurs where the Cu{sub 2}ZnSn{sub 0.5}Si{sub 0.5}S{sub 4} and Cu{sub 2}ZnSn{sub 0.2}Si{sub 0.8}S{sub 4} compounds co-exist. The optical bandgap increases continuously with the Si contentmore » in the whole series. This opens up the possibility to fine tune the absorption threshold and to adjust it to 1.7 eV for x∼0.5, the optimum value for the top cell of tandem solar devises to achieve high photovoltaic conversion efficiency. - Graphical abstract: Two solid solutions have been pointed out in the Cu{sub 2}Zn(Sn{sub 1−x}Si{sub x})S{sub 4} series with the kesterite and the enargite type structures. - Highlights: • New compounds in Cu{sub 2}Zn(Sn,Si)S{sub 4} series have been prepared. • Two solid solutions Cu{sub 2}ZnSn{sub 1−x}Si{sub x}S{sub 4} were identified for x≤0.5 and x≥0.8. • In the miscibility gap 2 phases co-exist with kesterite and enargite structure types. • The optical bandgap increases continuously with the Si-content in the whole series. • These materials could be envisioned as absorber in thin-film solar cells.« less
  • Electrical properties of solution processed Cu{sub 2}ZnSnS{sub 4} (CZTS) compound semiconductor thin film structures on molybdenum (Mo) coated glass substrates are investigated using Mott-Schottky and Impedance spectroscopy measurements at room temperature. These measurements are carried out in sodium sulfate (Na{sub 2}SO{sub 4}) electrolytic medium at pH ~ 9.5. The inversion/depletion/accumulation regions are clearly observed in CZTS semiconductor −Na{sub 2}SO{sub 4} electrolyte interface and measured flat band potential is ~ −0.27 V for CZTS thin film electrode. The positive slope of the depletion region confirms the intrinsic p-type characteristics of CZTS thinfilms with ~ 2.5× 10{sup 19} holes/m{sup 3}. The high frequencymore » impedance measurements showed ~ 30 Ohm electrolyte resistance for the investigated configuration.« less
  • The fabrication of environmental-friendly Cu{sub 2}ZnSnS{sub 4} (CZTS) thin films with pure kesterite phase is always a challenge to researchers in the field of solar cells. We introduce a simple non-vacuum sol-gel method to fabricate kesterite CZTS films. Ethylenediamine is used as the chelating agent and stabilizer and plays an important role in preparing stable precursor. X-ray diffraction, Raman and scanning electron microscopy studies suggest that the microstructure and optical properties of CZTS films depend strongly on annealing temperatures. The temperature dependence of conductivity of 500 °C annealed CZTS film shows that the Mott law dominates in the low temperature regionmore » and thermionic emission is predominant at high temperatures.« less
