“…It has a lot of potential application in the fabrication of photovoltaic devices such as window material, super-ionic conductor, electro-optical devices, optical filter, solar cell, lithium ion cells, thermoelectric converter, photo-thermal conversion, electroconductive electrodes, and microwave shielding coating [11,12]. Copper selenide is a metal chalcogenide semiconductor with a wide range of stoichiometric compositions and also with various crystallographic forms for each of these compositions.…”

Quaternary compound Cu 2 ZnSnSe 4 (CTZSe) which belonged to I 2 -II-IV-VI 4 group, without rare elements, can be considered as the perfect material for absorbing layer in eco-friendly solar cells due to low cost and high efficiency. The CTZSe powders were synthesized by hydrothermal coreduction method from metal chlorides and SeO 2 with reducing agent hydrazine hydrate at 160∼200 ∘ C. The phases of obtained products were analyzed by X-ray diffraction (XRD) and the size and morphology were observed by field emission scanning electron microscope (FESEM). Experimental results show that well crystallized Cu 2 ZnSnSe 4 powders without Se impurities can be obtained by reacting at 200 ∘ C for 90 h. The three strong XRD peaks of these products are corresponding to (112), (204), and (312) crystal planes, respectively. The morphologies of these products mostly show irregular polygon flakes with about 30∼40 nm thickness and 50∼200 nm diameters.

“…Therefore, many different methods have been reported for preparing cuprous selenide powders. Cuprous selenide powder with hexagonal plate shape and particle size of 1.3-2 mm was prepared using the hydrothermal method using CuSO 4 Á5H 2 O and SeO 2 as raw materials at 150 8C for 24 h [18]. Zhang et al [19,20] reported that binary metal chalcogenide nanocrystals could be successfully synthesized through reactions between an alkaline aqueous solution with dissolved elemental S, Se, or Te and an aqueous solution of metal complex at low temperature.…”
