本論文以探討層壓法製備反置型有機太陽能電池為目的，改進製程，首先是太陽能電池的材料選擇，以P3HT與ICBA作為下層材料及低能隙材料PSBTBT與PCBM作為上層，藉由串聯兩主動層以吸收不同光波段，達成單位面積上光轉換效率的提升。接著進行多層太陽能電池的元件製備，其中中間層之影響至關重要，本文中採用PEDOT:PSS PH1000與ZnO作為中間層材料，PH1000使用DMSO調整其電性，在後期的層壓法中採用再進一步添加D-sorbitol去調整其黏性；ZnO則採用較低的濃度使其嵌入電洞傳輸層之裂隙形成一保護層，最後再進行可行性測試，此處發現UVA光的照射對於中間層有相當大的影響，由於UVA使ZnO產生氧原子再復合的結果，改善其晶格也提升載子濃度，提升中間層的特性。
層壓法的目的除了縮短製程時間也避免兩主動層在典型旋塗製程中，重複地曝露於大氣中使主動層劣化或是肉眼不可見的溶劑影響，製程最後將兩試片置於以5×10-3torr與150℃以下之環境進行層壓法黏合，但由於分開製作兩太陽能電池，其製程方向完全相反，而材料親疏水性不匹配，金屬電極必須使用氧電漿調整親疏水性，則將銀電極轉換成金電極，於此產生反射光波段不同的差異，使光捕捉效應下降，可以預見短路電流密度的降低。
本文中除了成功製備典型旋塗製程的反置型多層有機太陽能電池，也成功將黏性電洞傳輸層應用於層壓法，製備出層壓法之多層有機太陽能電池，根據填充因子的提升，其效率相差無幾。

The objective of this thesis is to present fabrication of inverted tandem organic solar cells by a lamination process. The tandem structure of the solar cell fabricated with the front cell made of P3HT:ICBA and the rear cell made of low band gap materials of PSBTBT:PCBM. Each of the cells can be fabricated separately at the same time so that not only the entire fabrication duration can be significantly reduced, but also fabrication of the top cell will not affect or even attack the bottom cell due to the use of the same solvents. After completed fabrication of both the front and the rear cell the two cells can be hot impressed together in a vacuum at 5×10-3 torr with a temperature less than 150°C.The hole transport layer used in the front cell is PEDOT:PSS PH1000 that was modified by adding both D-sorbitol to increase the stickiness and the DMSO to increase conductivity. The selection of ZnO together with PEDOT:PSS PH1000 as IML can form a good protection for the bottom cell during fabrication of the top cell. In addition, the ZnO of the IML should be irradiated with UVA light and exposed in air to increase the carrier concentration, and demonstrate a good characteristic of contact with the hole transport layer. The tandem OSCs by lamination process exhibit the Voc of 1.43, the Jsc of 6.725mA/cm2, the FF of 0.572 and the PCE of 5.5%.
