CZTS???? ??????? ???? ??? ??????? ??????? ??????? Index. décimale : 530 Physique Résumé : The present work deals with the deposition of CZTS thin films and related devices by a simple and cheap technique such as Spray Pyrolysis (SP). For this purpose, a set of CZTS thin film was prepared using various deposition conditions in order to optimize the deposition conditions allow us to prepare suitable films devoted to the photovoltaic applications. The studied deposition parameters were the substrate temperature, deposition time, and copper and zinc salt concentrations. The structural analysis shows that the obtained films are polycrystalline; they exhibit a tetragonal structure with a preferential orientation along (112). However, the structural properties and secondary phases were affected by the deposition conditions. From the optical and electrical characterization results, we inferred that the deposited films have suitable optoelectronic properties for the photovoltaic applications, since they present a good absorption in the visible range coupled with a higher conductivity. Finally; the fabricated CZTS heterojunction with various back contacts show a rectification behavior, the G-f characterization reveals the presence of interface state at CZTS/ZnS interface with a state density in the order of 1010 eV-1cm-2. The addition of ZnO intrinsic layer enhances the heterojunction device properties. Whereas, the solar cells based CZTS/CdS annealed at 450 °C under H2S gas show the best solar cell efficiency about 0.43 % and a current density equal 9.8 mA/cm2.

Titre : Elaboration et caractérisation de couches absorbantes des cellules solaires en couches minces à base de Cu2ZnSnS4 Type de document : texte imprimé Auteurs : Ouarda Daranfed, Auteur ; Mohamed Salah Aida, Directeur de thèse Editeur : constantine [Algérie] : Université Constantine 1 Année de publication : 2013 Importance : 133 f.

Index. décimale : 530 Physique Résumé : Among the most promoter quaternary semiconductors for the thin film solar cells fabrication, the Cu2ZnSnS4. Our choice is oriented on the quaternary thin film Cu2ZnSnS4 (CZTS) as a new film absorber with good physical properties (band gap energy from 1.4 to 1.6 eV with a large absorption coefficient over 104 cm-1). In addition, whose impact on the environment is very harmful. This part is carried in order to optimize the different parameters and to understand the growth mechanism of films deposited by spray method. These layers
are analyzed by various techniques of characterization of materials.
We have repaired a set of CZTS thin film with variable conditions such as substrate temperature, deposition time and salt of Zn source. The various deposited characterizations have shown that the fundamental properties depend on the deposition conditions. The XRD spectra have shown that films obtained from Zinc acetate have a coexistence of crystalline phase orientation CZTS preferentially along the direction [112] and a phase secondary ZnSnO3. The value of the optic gap varies from 1.4 to 1.6 eV, one places the thin films of CZTS like a serious candidate for their use like absorbing layer in the cells solar in thin film.
The electrical measurements indicated that the films conductivity varies in [0.7 – 6 (Ω.cm)-1].Diplôme : Doctorat en sciences En ligne : ../theses/physique/DAR6331.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=6301 Elaboration et caractérisation de couches absorbantes des cellules solaires en couches minces à base de Cu2ZnSnS4 [texte imprimé] / Ouarda Daranfed, Auteur ; Mohamed Salah Aida, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2013 . - 133 f. ; 30 cm.
