起始原料在合成CIS和CIGS粉體 結晶相生成影響之研究
Effect of Precursors on the formation of crystalline phase of CIS and CIGS powders.
摘要
黃銅礦基太陽能電池有銅銦硒系列CuInSe2[CIS]和銅銦鎵硒系列Cu(In1-XGaX)(Se1-YSY)[CIGS]等兩大種類的化合物太陽能電池。在高光電效率和低材料成本的好處下，銅銦鎵硒太陽能電池值得繼續研究開發。本實驗採用三種不同的前驅物，製備CIS和CIGS粉體，利用XRD、SEM、EDS以及TEM等儀器鑑定其結晶相，成份比及粒子大小、表面型態。 選用CuCl2 ，InCl3， 和SeCl4三種鹽類製備CIS粉體的優點是可以調整成份比，使用[Cu4{Se2P(OiPr)2}4] 、[In{Se2P(OiPr)2}3]二種前驅物製備粉體的優點則為單一相產物。 利用銅銦鎵硒四元素粉體水熱方式製備CIGS，由於粉體無法完全溶解於溶劑，而CuCl2 ，InCl3， GaCl3 和SeCl4四種鹽類和[Cu4{Se2P(OiPr)2}4] 、[In{Se2P(OiPr)2}3]和GaCl3無機化合物可以溶於溶劑中，可以製備出單一相的CIGS粉體，選用鹽類的好處可以控制CIGS粉體成份比，無機化合物製備出的CIGS粉體較無其他雜相生成。

Solar cells with chalocopyrite structure have two major types: copper indium selenium series, CuInSe2[CIS], and copper indium gallium selenium series, Cu(In1-xGax)(Se1-ySy)[CIGS]. Due to the advantages of high photoelectric efficiency and low materials cost, it is worth to keep studying these two material systems. In this experiment, three kinds of different precursors were used to synthesize CIS and CIGS powder. XRD, SEM, EDS, and TEM were then used to analyze crystallization, composition, particle size, and morphology of powder products. The composition of the product can be adjusted when salts of CuCl2, InCl3, and SeCl4 were used to synthesize the CIS powder. The product can be single phase if precursors of [Cu4{Se2P(O’Pr) 2}4] and [In{Se2P(O’Pr) 2}3] were used. It is hard to synthesize CIGS powder by using Cu, In, Ga, and Se powder directly, because all these powder can not be completely dissolved into the solvent used in this experiment. The composition of the product can be adjusted when salts of CuCl2, InCl3, GaCl3 and SeCl4 were used to synthesize the CIGS powder. The product can be almost single phase if precursors of [Cu4{Se2P(O’Pr) 2}4], [In{Se2P(O’Pr) 2}3], and GaCl3 were used.
