摘要
以无机盐作为金属源(InCl_(3)、CuCl以及CS_(2)),采用溶剂热法制备CuInS_(2)纳米粒子,进一步采用易热解的铜、铟、硫金属有机前体作为可降解配体成膜交联剂,交联剂包覆铜铟硫纳米粒子得到前驱物墨水,然后通过旋涂法制备CuInS_(2)薄膜,最后对CuInS_(2)薄膜进行硒化,得到的CuInS_(x )Se_(2-x)(CISS)吸光层。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、热重(TG)和霍尔效应测试系统对CISS薄膜的结构和性质进行了研究。结果表明:硒化后的薄膜晶粒尺寸变大,仍为黄铜矿结构。霍尔效应分析表明,所制备的CISS薄膜可用于薄膜太阳能电池的吸收层。
CuInS_(2) nanoparticles were prepared by solvothermal method using inorganic salts as metal sources(InCl_3,CuCl and CS_2).Further,biodegradable organic precursors of copper,indium and sulfur metal were used as film crosslinking agents,which coated copper indium sulfur nanoparticles with crosslinking agents to obtain precursor ink,and then CuInS_(2) film was prepared by spin coating.Finally,Cu In S_(x) Se_(2-x)(CISS) light-absorbing layer was obtained by selenizing CuInS_(2) film.The structure and properties of CISS films were investigated by X-ray diffractometer(XRD),scanning electron microscope(SEM),thermogravimetric(TG) and Hall-effect testing.The results showed that the size of the selenized film was enlarged and the structure was still chalcopyrite.Hall-effect analysis showed that the prepared CISS film was suitable for the absorption layer of thin film solar cells.
