近年來因能源需求與日俱增，全世界都在找尋可用之新替代能源，加上全球各國對綠色能源大力的提倡，使得太陽能電池被大量研究與開發，使現今提升太陽能電池效率之結構與方法也越來越多，為了降低製造成本，本實驗多採用印刷方式來減低製作太陽能電池，以達成可大量製作與成本的降低。
本實驗主要分成兩大部分，第一部分利用印刷方式先定義出電極區域，再利用酸蝕刻達成在電極區內重摻雜、非電極區內輕摻雜，再利用印刷的方式在正面印刷銀漿，而於矽晶片背面印刷鋁漿，製作出低成本之選擇性太陽能電池，此結構可以有效的提升短波長之光子吸收，以提升太陽能電池之效率。第二部分在於定義出的電極區域內，使用45% KOH在80℃下進行蝕刻，蝕刻出30um深的溝槽，此結構可以提升太陽能電池在長波段之載子收集率，以提升電流與填充因子，製作出埋入式電極太陽能電池(buried contact solar cell ,BSCS) 。
