本論文將以 Pentacene 作為主動層兼吸光層搭配 SubPc、C60 作為其餘之吸光材料，
補足能夠於全可見光波段的光吸收效果，且利用三者間造成的能階差，來提升光電參數。
第一部分，為了要讓 SubPc、C60 兩種材料在不同鍍率下和主動層的搭配使可見光
吸收效果能夠達到最大化，分別製作單層(SubPc、C60)、雙層(Pentacene/SubPc)、三層結
構(Pentacene/SubPc/C60)的材料片進行 Uv-Visible 量測，並量測出 SubPc、C60 最佳鍍率
為 0.3 Å/s 的吸收條件。
第二部分以 Pentacene 為主動層兼吸光層搭配 SiO2閘極絕緣層為基礎上製作 SubPc
及 C60 吸光材料，並在厚度變化下調變出 SubPC 40 nm 及 C60 20 nm 的條件下擁有最好
的響應度、靈敏值、外部量子效率及偵測度，並以 PL 及 AFM 分析，加以佐證。
最後為了更進一步提高光電特性，製作出有機雙閘極絕緣層 PVA / PVP，利用 PVA
的 High-K 特性能夠提高電流值並維持住操作電壓且在上層搭配交聯後的 PVP 形成疏
水的表面，使主動層(Pentacene)成長排列更好，藉此提高元件的載子遷移率(Mobility, µ)，
來減少光生載子的複合機率，達到光響應度為 122。

In this research, Pentacene is used as the active layer and the light-absorbing layer. Moreover, SubPc and C60 are used as the other light-absorbing materials to meet the light absorption effect in the entire visible light band and use the energy level difference caused by the three materials to improve the optoelectronic parameters.
First of all, in order to maximize the visible light absorption effect of the two materials (SubPc, C60) under different deposition rates with the active layer. We fabricated a single-layer (SubPc, C60), double-layer (Pentacene/SubPc), and tri-layer structure (Pentacene/SubPc/C60) were subjected to Uv-Visible measurement. The absorption conditions of the optimal rate of SubPc and C60 were measured at 0.3 Å/s.
Secondly, pentacene is the active and light absorption layer, subjoins SubPc and C60 over the pentacene, and is based on the SiO2 gate insulating layer to make the OPT. Under the modulation of different thicknesses, SubPc 40 nm and C60 20 nm were fabricated with the best responsivity, sensitivity, external quantum efficiency, and detection, confirmed by PL and AFM analysis.
Lastly, an organic double-gate insulating layer PVA/PVP was fabricated to improve the
optoelectronic properties further. The high-K characteristic of PVA could be increased current and maintained the operating voltage. On the other hand, the top layer of cross-linked PVP could form a hydrophobic surface. Therefore, the active layer (Pentacene) could grow and arranges better on a hydrophobic surface, thereby increasing the carrier mobility (µ) of the device, reducing the recombination probability of photogenerated carriers, and achieving a photoresponsivity of 122.
