本研究中，使用三種不同的材料製作多層膜有機光電元件，分別是以噻吩為主體的共軛高分子，3-羥基噻吩聚合物(poly(thiophene-3-acetic acid), PTAA)作為電子貢獻體(donor)，以及碳六十(fullerene[60], C60)及砒碇化碳六十(pyridine-functionalized fullerene[60], C60Py)為電子接受體(acceptor)，利用靜電分子自組裝技術(self-assembled multilayers)及逐層電沉積技術(layer-by-layer electrodeposition)製造多層膜有機光電元件。
分子自組裝技術藉由不同的參數，例如：溶液的酸鹼值，浸泡的時間，高分子電解質(鹽類)濃度，可在奈米尺度下控制多層膜結構中單層膜之厚度，利用分子自主裝技術製造C60Py/PTAA多層膜有機光電元件具有大量的介面面積，有助於電子的分離與傳遞。利用分子自組裝技術調整電子貢獻體與電子接受體的比例，比例調整的精確程度可達分子等級，製造出具濃度梯度的多層膜有激光電元件。本研究亦利用電壓輔助的方式製作C60Py的濃度梯度，製造出具濃度梯度之多層膜有機光電元件。C60/PTAA有機光電元件則利用逐層電沉積技術製備，元件中C60的濃度梯度結構亦利用不同的外加電場強度製作。

Multilayers organic photoelectric devices constructed by the electrostatic Self-Assembled Multilayers (SAMs) technology and Layer-by-Layer Electrodeposition were demonstrated. Three kinds of materials utilized to fabricate the multilayers organic photoelectric devices are the thiophene-based conjugated polyelectrolyte, poly(thiophene-3-acetic acid) (PTAA) severed as the electron donor; the fullerene[60] (C60) and pyridine-functionalized fullerene[60] (C60Py) severed as the electron acceptors. The C60Py/PTAA multilayers organic photoelectric devices were fabricated by SAMs. By controlling deposition parameters, such as pH values of solutions, concentrations of polyelectrolytes/salts, and the dipping time, SAMs technology are capable of manipulating the thickness of each single bilayer in nano scales. While the SAMs fabrication provides a large amount of interfacial area for the effective charge separation, the SAMs structures with concentration gradients in the donor and acceptor ratio were accurately controlled and manipulated in the molecular level. In this study, the voltage-assisted technology was developed to construct the concentration gradient of C60Py in SAMs processes. The C60/PTAA multilayer organic photoelectric devices were prepared by layer-by-layer electrodeposition. Concentration gradients of C60 were fabricated by various applied voltages as layer-by-layer electrodeposition.
