本實驗是利用熔煉法來製成 Cu(InGa)Se2 及CuInSe2使其晶粒增大。首先將銅、銦、鎵、硒四種純元素調配成Cu-poor、Stoichiometric、Cu-rich成份以及一份銅、銦、硒三種純元素調配成Stoichiometric成份，裝入石英管內並進行封管，接著利用高溫爐來進行熔煉，使其熔煉產生出具有大晶粒的Cu(InGa)Se2 四元化合物及CuInSe2三元化合物。原始設計之原子百分比CIGS為0.6、1.0、1.2，CIS為1.0，經過熔煉後之原子百分比變成0.63、1.02、1.22、1.07，與原先設計之原子比差異不大。根據本實驗室先前實驗結果可比較出，各種成份經由SEM可得出晶粒大小約100µm~400µm之間，與本實驗室先前的5µm增大了許多。在XRD分析下在(112)特徵峰下皆產生黃銅礦結構，並且比較Cu(InGa)Se2 四元化合物及CuInSe2 三元化合物兩者的Stoichiometric成份，可得知CuInSe2三元化合物可得到較大顆的晶粒，且結晶性也較好。

In this experiment, the melting method was used to make Cu (InGa) Se2 and CuInSe2 to increase the grain size. First, the four pure elements of copper, indium, gallium, and selenium are blended into Cu-poor, Stoichiometric, and Cu-rich components, and a portion of the three pure elements of copper, indium, and selenium are blended into Stoichiometric ingredients. Then, it is melted in a high-temperature furnace to produce Cu (InGa) Se2 quaternary compounds and CuInSe2 ternary compounds with large crystal grains.
The atomic percentage CIGS of the original design is 0.6, 1.0, 1.2, and CIS is 1.0. After sintering, the atomic percentage becomes 0.63, 1.02, 1.22, 1.07, which is not much different from the atomic ratio of the original design. According to the previous experimental results of our laboratory, the SEM observation of various components can show that the grain size is between 100µm and 400µm, which is much larger than the previous 5µm in our laboratory. After melting, the test piece produced a chalcopyrite structure under the (112) characteristic peak under XRD analysis, and compared the Stoichiometric composition of Cu (InGa) Se2 quaternary compound and CuInSe2 ternary compound, it can be known that CuInSe2 ternary compound Larger grains can be obtained and the crystallinity is better.
