本研究針對矽晶型太陽能模組進行資源再生研究，研究主軸分為四大部分，第一部分為太陽能模組前處理，將太陽能模組鋼化玻璃與背板分離後，以500°C熱處理，將聚乙烯醋酸乙烯酯(EVA)去除，蒐集矽晶型太陽能電池片(PV cell)與鍍錫銅帶(PV Ribbon)。
第二部分為矽晶型太陽能電池片雜質去除與純化研究，藉由對電池片特性分析結果規劃後續研究流程，並以5M硝酸與1M氫氧化鉀進行浸漬流程，對於電池片表層銀、鋁浸漬效率達99.4%與98.9%，並得到純度99.84%矽資源。
第三部分為鍍錫銅帶金屬溶出與分離純化研究，藉由對鍍錫銅帶特性分析後，以3M鹽酸將鍍錫銅帶直接酸溶浸漬與鍍層先行分離兩種方式處理，直接浸漬可將銀金屬先行分離，並以溶媒萃取技術分選其餘浸漬後的金屬離子。利用鍍層先行分離技術可直接將鍍錫銅帶內金屬銅與鉛、錫鍍層分離回收，得純度99.5%以上之金屬銅，鍍層則會以直接浸漬最佳參數浸漬溶出，接續溶媒萃取技術分選金屬離子。溶媒萃取流程中使用TBP進行第一階段萃取分離，將錫離子萃取至油相，銅、鉛離子留在萃餘液中，再利用硝酸做為反萃劑，將錫離子反萃取回水相。銅、鉛離子則是利用LIX984N進行第二階段萃取分離，將銅離子萃取至油相，鉛離子留在萃餘液中，再利用硫酸做為反萃劑，將銅離子反萃取回水相。
第四部份為矽晶型太陽能電池片和鍍錫銅帶金屬產物析出研究，將銀、銅、錫、鉛離子利用化學沉澱結晶法，加入氯化鈉及氫氧化氨進行沉澱反應，得到氧化銀與其他金屬氫氧化物，再利用還原法與煅燒法得到金屬銀、氧化銅、氧化錫與氧化鉛產物，其純度分別為98.85%、99.7%、99.68%、99.47%。

With the rapid increase of PV module installation, the methods for recovering waste solar generators should be studied as the backup of the PV market. This study provided a valuable materials resource circulation process from waste crystalline silicon PV module. The process was divided into four groups to effectively recycle PV module, including pretreatment, PV cell purification, PV ribbon metals separation, and metals purification. In pretreatment part, tempered glass and back sheets were removed from PV module by organic solvent. After removing tempered glass, PV module was heating to 500°C to eliminate EVA resin on the surface of the module. The module was separated into two materials, PV ribbon and PV cell. In PV cell purification part, two-step leaching was employed to dissolve the impurity such as Al, Ag in PV cell. After the process, the purity of silicon was 99.84%. In PV ribbon metals separation process, leaching and polishing were both studied and compared. The agent with Cu, Pb, Sn ions after leaching was separated through the extraction process. In the final metal purification step, CuO, PbO, SnO2 were obtained by chemical precipitation and calcination. Ag was obtained by precipitation and chemical reduction. The purity of CuO, PbO, SnO2 and Ag are over 99%.
