Effect of Annealing on Physical Properties of Cu2ZnSnS4 (CZTS) Thin Films for Solar Cell Applications
Cu2ZnSnS4 (CZTS) thin films were prepared by directly sputteringCu (In,Ga)Se2 quaternary target consisting of (Cu: 25%, Zn: 12.5%, Sn; 12.5%and S: 50%). The composition and structure of CZTS layers have beeninvestigated after annealing at 200 0C, 350 0C and 500 0C under vacuum. Theresults show that recrystallization of the CZTS thin film occurs and increasingthe grain size with a preferred orie...
متن کاملCu(2)ZnSnS(4)-Pt and Cu(2)ZnSnS(4)-Au heterostructured nanoparticles for photocatalytic water splitting and pollutant degradation.
Cu2ZnSnS4, based on abundant and environmental friendly elements and with a direct band gap of 1.5 eV, is a main candidate material for solar energy conversion through both photovoltaics and photocatalysis. We detail here the synthesis of quasi-spherical Cu2ZnSnS4 nanoparticles with unprecedented narrow size distributions. We further detail their use as seeds to produce CZTS-Au and CZTS-Pt hete...
متن کاملWurtzite copper-zinc-tin sulfide as a superior counter electrode material for dye-sensitized solar cells
Wurtzite and kesterite Cu2ZnSnS4 (CZTS) nanocrystals were employed as counter electrode (CE) materials for dye-sensitized solar cells (DSSCs). Compared to kesterite CZTS, the wurtzite CZTS exhibited higher electrocatalytic activity for catalyzing reduction of iodide electrolyte and better conductivity. Accordingly, the DSSC with wurtzite CZTS CE generated higher power conversion efficiency (6.8...
متن کاملSpray pyrolysis of CZTS nanoplatelets.
We demonstrate that copper-zinc-tin-sulphide nanoplatelets can be directly grown onto a molybdenum-coated substrate using spray pyrolysis starting from a mixture of metal thiocarbamates precursors. The structure and phase purity of the nanoplatelets is discussed in detail.
متن کاملWell-Dispersed Cu2ZnSnS4 Nanocrystals Synthesized from Alcohols and Their Applications for Polymer Photovoltaics
In this work, we report on a simple non-injection synthesis routine for the preparation of well-dispersed monocrystalline Cu2ZnSnS4 (CZTS) nanoparticles (NPs). The nanocrystal morphology was investigated by scanning and transmission electron microscopy, and its phase composition was studied by X-ray diffraction and Raman analyses. Cu2ZnSnS4 nanoparticles prepared using ethanolamine and diethano...
