Czts Thin Films

Cu2ZnSnS4(CZTS) is a promising semiconductor material for photovoltaic applications,with excellent optical and electronic properties while boasting a nontoxic, inexpensive, andabundant elemental composition. Previous high‐quality CZTS thin films often required eithervacuum‐based deposition processes or the use of organic ligands/solvents for ink formulation,which are associated with various issues regarding performance or economic feasibility. To addressthese issues, an alternative method for depositing CZTS thin films using an aqueous‐basednanoparticle suspension is demonstrated in this work. Nanoparticles of constituent binary sulfides(CuxS and ZnS) are stabilized in an ink using tin(IV)‐based, metal chalcogenide complexes such as[Sn2S6]4‐. This research paper provides a systematic study of the nanoparticle synthesis and inkformulation via the enabling role of the tin chalcogenide complexing power, the deposition of highqualityCZTS thin films via spin coating and annealing under sulfur vapor atmosphere, theirstructural characterization in terms of nanocrystal phase, morphology, microstructure, anddensification, and their resultant optoelectronic properties.

AbstractCopper zinc tin sulfide (Cu2ZnSnS4, CZTS) consists of abundant and cheap elements and is therefore a very promising alternative to semiconductors based on Ga or In as solar absorber material. In addition it displays very beneficial properties like a high optical absorption coefficient and an ideal band gap for photovoltaic applications. In this contribution we present the preparation of CZTS thin films from metal salts (copper(I) iodide, zinc(II) acetate and tin(II) chloride) and thioacetamide as sulfur source by a solution based precursor method. CZTS solar cells based on these films as absorber layer with a simple ITO/CZTS/CdS/Al assembly are fabricated and characterized. Efficiencies up to 0.5% were achieved demonstrating the potential of this precursor method for the preparation of CZTS thin films for photovoltaic applications.

Photovoltaic Applications

Tin mono selenide (SnSe) with an energy gap of about 1 eV is a potential material for photovoltaic applications. Various authors have studied the structure, electronic and photoelectronic properties of thin films of SnSe grown by various deposition techniques. However, for practical photovoltaic junctions the electrical properties of SnSe films need improvement. We have carried out investigations into the properties of flash evaporated SnSe films. In this paper we report our results on the structure, which plays a dominant role on the electrical properties of thin films by TEM, SEM, and electron diffraction (ED).Thin films of SnSe were deposited by flash evaporation of SnSe fine powder prepared from high purity Sn and Se, onto glass, mica and KCl substrates in a vacuum of 2Ø micro Torr. A 15% HF + 2Ø% HNO3 solution was used to detach SnSe film from the glass and mica substrates whereas the film deposited on KCl substrate was floated over an ethanol water mixture by dissolution of KCl. The floating films were picked up on the grids for their EM analysis.
