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.

ABSTRACTThe lead free double perovskite Cs2AgBiBr6 is an upcoming alternative to lead based perovskites as absorber material in perovskite solar cells. So far, the majority of investigations on this interesting material have focused on polycrystalline powders and single crystals. We present vapor and solution based approaches for the preparation of Cs2AgBiBr6 thin films. Sequential vapor deposition processes starting from different precursors are shown and their weaknesses are discussed. Single source evaporation of Cs2AgBiBr6 and sequential deposition of Cs3Bi2Br9 and AgBr result in the formation of the double perovskite phase. Additionally, we show the possibility of the preparation of planar Cs2AgBiBr6 thin films by spin coating.

Czts Thin Films

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.

AbstractWe report the growth of Cu2ZnSnS4 (CZTS) thin films by electrodeposition in ionic liquid. Sulfurization was performed in elementary sulfur vapor environment at 450°C for 2 hours. The X-ray diffraction analysis indicated that the film has a stannite structure with preferred grain orientation along (112). Photo-absorption measurement of the sample was performed from 500 nm to 990 nm. It is found that the energy bandgap of the film is about 1.49eV and the absorption coefficient is found to be of the order of 104cm-1.
