摘要

有機太陽能電池因為具有質量輕盈易於攜帶、製作過程簡易且附有元件可撓性之應用等優點，所以是近年來研究低成本太陽能電池的重要領域之一。
本論文研究主要分為兩大部分，第一部分是將之前超薄吸收層太陽能電池(ETA solar cell)的模擬結果製作成元件，因此我們使用奈米小球及凝膠狀(Sol-gel) IGZO經過退火的方式製作成多層的指叉狀結構當作電子傳輸層，之後利用浸泡成膜的方式將P3HT；或是利用刮刀塗佈將PBDTTT-C-T成膜在指叉狀結構的表面形成超薄吸收層，接下來利用TFB；或是使用PEDOT：PSS材料藉由刮刀塗佈將指叉狀的結構填滿當作電洞傳輸層，並且鍍上電極完成此元件，其中會使F4TCNQ 針對TFB進行濃度摻雜的改變，以討論其元件的轉換效率之變化。
第二部分是以凝膠狀IGZO為電子傳輸層，之後利用P3HT: PCBM溶於高沸點溶劑(1,2-dichlorobenzen)DCB中並且以旋轉塗佈以及慢乾的方式作為主動層，完成有機無機混合太陽能電池，並且使用F4TCNQ對P3HT:PCBM進行摻雜及利用IGZO中In、Ga、Zn彼此間的比例調變來改變此結構的開路電壓(Voc)，藉此達到更好的轉換效率。

The Organic solar cell is one of the important areas of research low-cost solar cells in recent years. It’s because of component is quality of light and easy to carry, flexible application of the production process simple.
This thesis is divided into two parts, first part will be made before ultra-thin absorber layer solar cell (ETA solar cell) of the simulation results into components, so we use the nano-ball and sol-gel IGZO produced the multilayer of porous structure as the electron transport layer after annealing, and then dip-coating the P3HT; or blade coating the PBDTTT-C-T film on the surface of the porous structure to form a ultra -thin absorption layer, then use TFB; Or the PEDOT: PSS materials by blade coating to fill up the porous structure as the hole transport layer, finally use the evaporating to plated the electrode to complete this component. We also make the F4TCNQ for TFB doping to change the carrier concentration to discuss the conversion efficiency of its components change.
The second part it’s use the Sol-gel IGZO as the electron transport layer, and followed by use of P3HT : PCBM dissolve in the high boiling point solvent DCB as the active layer by using the spin coating and solvent-annealing to complete the organic-inorganic hybrid solar cells. Finally the P3HT and PCBM are doped with the F4TCNQ and to change the sol-gel IGZO each elements ratio to modulate the open circuit voltage (Voc) of the structure in order to achieve better conversion efficiency.
