Title: Nanocrystalline Cu{sub 2}ZnSnSe{sub 4} thin films for solar cells application: Microdiffraction and structural characterization

Abstract

This work presents a study of the structural characterization of Cu{sub 2}ZnSnSe{sub 4} (CZTSe) thin films by X-ray diffraction (XRD) and microdiffraction measurements. Samples were deposited varying both mass (M{sub X}) and substrate temperature (T{sub S}) at which the Cu and ZnSe composites were evaporated. CZTSe samples were deposited by co-evaporation method in three stages. From XRD measurements, it was possible to establish, with increased Ts, the presence of binary phases associated with the quaternary composite during the material's growth process. A stannite-type structure in Cu{sub 2}ZnSnSe{sub 4} thin films and sizes of the crystallites varying between 30 and 40 nm were obtained. X-ray microdiffraction was used to investigate interface orientations and strain distributions when deposition parameters were varied. It was found that around the main peak, 2ϴ = 27.1°, the Cu{sub 1.8}Se and ZnSe binary phases predominate, which are formed during the subsequent material selenization stage. A Raman spectroscopy study revealed Raman shifts associated with the binary composites observed via XRD.

  • Indium tin oxide (ITO) thin films prepared by rf sputtering were annealed in several temperatures. The electrical, optical and structural properties of these films are systematically investigated. The post annealing of the samples lead to considerably higher electrical conductivity, better optical transparency and larger grain size for the films. In an optimum annealing temperature of 400 deg. C, we have found that a maximized conductivity of films is achieved without a remarkable loss in their transparency. The sheet resistance of 2.3 {omega}/{open_square} and average grain size of 30 nm, are the results of the optimized post processing of films. Themore » investigation for microstructure of films investigated by X-ray diffraction measurement (XRD) shows that a preferential crystal growth toward the (2 2 2) orientation takes place when the annealing temperature increases to 400 deg. C.« less
  • Films of CuInSe{sub 2} were deposited onto glass substrates by a hot wall deposition method using bulk CuInSe{sub 2} as a source material. All the deposited CuInSe{sub 2} films were found to be polycrystalline in nature exhibiting the chalcopyrite structure with the crystallite orientation along (101),(112),(103),(211),(220),(312) and (400) directions. The photocurrent was found to increase with increase in film thickness and also with increase of light intensity. Photocurrent spectra show a peak related to the band-to-band transition. The spectral response of CuInSe{sub 2} thin films was studied by allowing the radiation to pass through a series of interference filters inmore » the wavelength range 700-1200 nm. Films of higher thickness exhibited higher photosensitivity while low thickness films exhibited moderate photosensitivity. CuInSe{sub 2}-based Solar cells with different types of buffer layers such as CdS, CdSe, CuInSe{sub 2} and CdSe{sub 0.7}Te{sub 0.3} were fabricated. The current and voltage were measured using an optical power meter and an electrometer respectively. The fabricated solar cells were illuminated using 100 mW/cm2 white light under AM1 conditions.« less
  • Nanocrystalline cadmium sulfide (CdS) and zinc cadmium sulfide (ZnCdS) thin films have been grown via simple and low cost dip coating technique. The prepared films are characterized by X-ray diffraction (XRD), atomic force microscopic (AFM) and UV-VIS spectrophotometer techniques to reveal their structural, morphological and optical properties. XRD shows that both samples grown have zinc blende structure. The grain size is calculated as 6.2 and 8 nm using Scherrer’s formula. The band gap value of CdS and CdZnS film is estimated to be 2.58 and 2.69 eV respectively by UV-vis spectroscopy. Photoelectrochemical (PEC) investigations are carried out using cell configuration asmore » n-CdZnS/(1M NaOH + 1M Na2S + 1M S)/C. The photovoltaic output characteristic is used to calculate fill-factor (FF) and solar conversion efficiency (η)« less
  • The structure and photoelectrochemical properties of TiO{sub 2} films deposited onto SnO{sub 2} conducting glass from the ambient hydrolysis of TiCl{sub 4} and annealed at temperatures ranging from 100 to 500 C were studied by Raman spectroscopy. X-ray diffraction (XRD), transmission electron microscopy (TEM), intensity-modulated photovoltage spectroscopy (IMVS), and intensity-modulated photocurrent spectroscopy (IMPS) measurements. Analysis of the XRD and Raman spectra shows that TiCl{sub 4}-produced TiO{sub 2} films consist of rod-shaped particles that grow with an increasing annealing temperature. The AM-1.5 short-circuit photocurrent J{sub sc} and open-circuit photovoltage V{sub oc} of Ru[LL{prime}(NCS){sub 2}]-sensitized (L = 2,2{prime}-bypyridyl-4,4{prime}-dicarboxylic acid, L{prime} = 2,2{prime}-bipyridyl-4,4-ditetrabutylammoniumcarboxylate)more » 4.5 {micro}m thick rutile films increase significantly with annealing temperature, from 1.1 mA/cm{sup 2} and 602 mV at 100 C to 8.7 mA/cm{sup 2} and 670 mV at 500 C. Studies of the incident photon-to-current conversion efficiency (IPCE), the photocurrent-voltage characteristics, the optical appearance, the water content, and the particle size of the films indicate that the increase of both J{sub sc} and V{sub oc} with annealing temperature is due, in part, to increased dye adsorption resulting from the evaporation of surface water and the improved light-scattering properties of the film associated with the growth of rutile particles. Raman and XRD measurements and other observations indicate that treating transparent nanocrystalline anatase TiO{sub 2} electrodes with TiCl{sub 4} produces a translucent overlayer of rutile TiO{sub 2}. The increased film thickness and light-scattering characteristics of the rutile overlayer may explain, in part, the improved IPCE observed for dye-sensitized TiCl{sub 4}-treated nanocrystalline anatase TiO{sub 2} electrodes.« less
