    摘要:

    以Cu，In，Ga，Se單質(zhì)為原料用自蔓延高溫合成法制備CuIn0.7Ga0.3Se2粉末。通過X射線衍射、光電子能譜、能量散射X射線分析、激光拉曼光譜等分析方法對產(chǎn)物的組成、結(jié)構(gòu)和成分進(jìn)行表征。結(jié)果表明，反應(yīng)物投料比例，合成氣氛壓力等因素對合成產(chǎn)物化學(xué)計(jì)量配比有顯著的影響。利用自蔓延高溫合成方法可以獲得精確化學(xué)計(jì)量配比、單相黃銅礦結(jié)構(gòu)的CuIn0.7Ga0.3Se2。

    Abstract:

    CuIn0.7Ga0.3Se2 (CIGS) was synthesized using Cu, In, Ga and Se powders as starting materials by self-propagating high-temperature synthesis method (SHS). The phase and crystallographic structure，chemical composition of the products were characterized by X-ray Diffraction, X-ray Photoelectron Spectroscopy, Energy Dispersive X-ray spectrometer and Laser Raman Spectroscopy. The results show different factors in this process such as reactant ratio, atmosphere pressure etc. obviously influence the stoichiometric composition of the products. An accurate stoichiometric, single-phase chalcopyrite-type CIGS can be prepared by SHS.
