CZTSe薄膜太陽能電池，結構類似於同為太陽能電池材料的CIGS
的結構且價格相對低廉，因此CZTSe 被喻為第三代薄膜太陽能電池
的候補技術。
本研究使用金屬粉末做為原料，在非真空的製程環境下使用熱迴
流偶合油相法合成Cu2ZnSnSe4 (CZTSe) 漿料、粉體；在反應合成溫
度相同的情況下，改變多種製程條件，例如不同反應溶劑、反應時間與硒化條件等，從中探討取得最佳合成條件、製備生成的粉末與薄膜以XRD、SEM、TEM、EDS、Raman、UV-Vis 進行特性分析，經實
驗結果指出以IPDA 作為反應溶劑，能與金屬粉末充分反應，經過反
應20 小時後，可避免二元相或三元相殘留，合成出單一Cu2ZnSnSe4
漿料(粉末)。其短時間合成中所產生的前驅物亦可透過硒化處理，獲得改善形成良好的Cu2ZnSnSe4 薄膜，可大幅縮減製作CZTSe 吸收層所需的時間。

Most of Cu2ZnSnSe4 absorber layer prepared by ink process are described as followed:
First, in the beginning of synthesized process, high boiling point chelating agent with N-H bending modes is necessary for the formation of metal complex phase, after the reactions temperature were maintained for enough time, the reactions mixture were cooled to room temperature,
acetone was added to precipitate the nanocrystal products. Then, the precipitate was centrifuged and washed with distilled water and absolute ethanol several times to remove by-products. The product was filtered off and then vacuum-dried at 80 oC in Oven, the above process of obtaining CZTSe nano powders are very complicated. At the end, the as-prepared CZTSe particles were mixed with dispersant and binder to increase viscosity, the ink for screen printing was prepared.
In this work, we report the application of the elemental
solvothermal synthesized process in favor of obtaining CZTSe nano ink,CZTSe nano inks were successfully synthesized by using metal powders under N2 atmosphere, the synthesized nano ink was printed on the substrates without additive binders and adjunct, this absorber layer deposited process is convenient than most of reported ink printing process.
