Summary:The present invention provides a unique method for producing micro-structured quaternary chalcogenide Cu2NiSnS4 material (130/3) in an improved marigold shape by using a solvent heat method. The present invention is able to form a sample (108/2) by evenly agitating 0.1M of copper (II) chloride dehydrate (102/1), 0.05M of nickel (II) chloride hexahydrate (102/2), 0.05M of tin (IV) chloride pentahydrate (102/3) in a chamber (118/2) by using deionized water and ethanol. Citric acid (110/2) is added to the sample (108/2) and agitated for 20 minutes. In addition, another sample (116/2) is produced by adding 0.4M of thiourea (114/2) into the chamber (118/2) and agitating for one hour. Black precipitate (124/3) is produced in the muffle furnace (120) by heating the sample (116/2). Ethanol and methanol solutions are used to filter (126) the black precipitate (124/3). Here, the filtered black precipitate is dried in a hot air oven (128), thereby producing the micro-structured Cu2NiSnS4 material (130/3) in a marigold shape. 본 발명은 용매열 방법을 이용하여 개선된 금잔화 형상의 마이크로-구조화된 4요소 칼코제나이드 Cu2NiSnS4 재료(130/3)를 생산하는 독특한 방법을 제공한다. 0.1M 구리(II) 클로라이드 디하이드레이트(102/1), 0.05M 니켈(II) 클로라이드 헥사하이드레이트(102/2), 0.05M 주석 (IV) 클로라이드 펜타하이드레이트(102/3)가, 챔버(118/2) 내부에서 탈이온수 및 에탄올로 일정하게 교반함으로써 혼합되어 샘플(108/2)를 형성한다. 시트르산(110/2)이 상기 샘플(108/2)에 첨가되고 20분 동안 교반된다. 또한 0.4M 티오우레아(114/2)가 상기 챔버(118/2) 내에 첨가되고 다시 한 시간 동안 교반함으로써 다른 샘플(116/2)를 생산한다. 흑색 침전물(124/3)이 머플로(120) 내부에서 상기 샘플(116/2)를 가열함으로써 생산된다. 에탄올 및 메탄올 용액은 상기 흑색 침전물(124/3)을 여과(126)하기 위해 이용되며, 여기에서, 상기 여과된 흑색 침전물은 뜨거운 공기 오븐(128)에서 건조되며, 이에 의해 금잔화 형상의 마이크로-구조화된 Cu2NiSnS4 재료(130/3)를 생산한다.
