本實驗中我們採用Y.Qian等人在Advanced Materials發表的CuInSe2製備方式合成不同形貌的CuInSe2粉末。藉由改變反應時間,可以控制奈米線的長度,進而影響CuInSe2材料能階的分布情形。另外我們改變粉末製備配方,用相同的製程方法合成了CuGaSe2奈米粉末,以作為提昇元件效率的材料。
合成溫度180℃,反應時間48小時是合成CuInSe2球狀粉末的最佳條件;而在溫度180℃,反應時間42小時下,則是合成CuInSe2柱狀粉末的最佳條件。在合成溫度在210℃,反應時間24小時下,我們成功合成了CuGaSe2奈米粉末。而在粉末的生長機制中,我們推測粉末中的二次相是影響粉末生長的重要因素,也影響了粉末粒徑的大小。

In this experiment,we used the solvothermal method that described by Y.Qian et al,to synthesize nano powder which have different morphology.We had demonstrated it that by controlling and changing the temperature,reaction time and washing agents,to control the size and it leads to the change of the energy gap.In others,we changed the ,and used the same method to synthesize CuGaSe2 powder.It was used to improve the efficirncy of the solar cell devices.
The synthetic temperature 180℃ and rection time 48hrs are the best condition in nano spherical powder experiment.The synthetic temperature 180℃ and reaction time 42hrsare the best condition in nano rods experiment.The synthetic temperature 210℃ and reation time 24hrs,we synthesize CuGaSe2.And in the kinetic mechanism of nano powder,we think that the second phase is the important factor that influence the growth of nano poweder,and also influence the size of powder.
