| dc.description.abstract | 近年來由於環保意識的重視和石化燃料的逐漸枯竭，以及曾在1973年發生了石油危機，這讓世界各國意識到能源開發的重要性，所以各地學者致力於研究再生能源，而再生能源中的太陽能是一個具有潛力的研究方向，其中以鈣鈦礦太陽能電池(perovskite solar cell, PSC)的研究越來越受到重視，本團隊嘗試以新型省步驟合成途徑，製備出鈣鈦礦太陽能電池中的電洞傳輸層(hole-transporting material, HTM)。
二噻吩并噻吩是光電材料中重要的單元，在有機太陽能電池(organic photovoltaic, OPV)、有機發光二極體(organic light-emitting diode, OLED)、有機場效電晶體(organic field-effect transistor, OFET)及染料敏化太陽能電池(dye-sensitized solar cell, DSSC)等領域之應用極為廣泛，且光電性質上也有出色的表現，因此本團隊嘗試開發以二噻吩并噻吩作為核心結構，連接末端基合成出有機共軛小分子，並應用於鈣鈦礦太陽能電池之電洞傳輸層。
材料合成方面，二噻吩并噻吩(dithienothiophene, DTT)在文獻中大多使用步驟較繁瑣、成本昂貴的傳統方法。有別於傳統合成途徑，本團隊以低成本、方法簡單為目標，嘗試使用低價銅觸媒下進行碳-硫合環出二噻吩并噻吩，並且篩選不同硫原子來源、配位基及溶劑來尋找出最佳化條件為本篇重點之一，再利用鈀催化劑及銅催化劑直接碳氫鍵芳香環化合成出KHC01-KHC04，最後以此四種有機小分子實際應用在反式鈣鈦礦太陽能電池的電洞傳輸層，並探討其光電性質的相關表現。 | zh_TW |
| dc.description.abstract | In recent years, due to the increasing emphasis on environmental awareness and the gradual depletion of petrochemical fuels, as well as the oil crisis of 1973, countries around the world have realized the importance of energy development. As a result, scholars worldwide have been dedicated to researching renewable energy sources, with solar energy being a particularly promising area of study. Among renewable energy sources, the research on perovskite solar cells (PSC) has been receiving increasing attention. Our team is attempting to synthesize the hole-transporting material (HTM) for perovskite solar cells using a novel, more efficient synthesis approach.
Dithienothiophene (DTT) is an essential unit in optoelectronic materials, widely applied in various fields such as organic photovoltaics (OPV), organic light-emitting diodes (OLED), organic field-effect transistors (OFET), and dye-sensitized solar cells (DSSC). It exhibits excellent optoelectronic properties. Therefore, our team is striving to develop organic conjugated small molecules by using dithienothiophene as the core structure, with appended end groups, and apply them as the hole-transporting material in perovskite solar cells.
In terms of material synthesis, the traditional methods for synthesizing dithienothiophene described in the literature are often cumbersome and costly. Diverging from the conventional synthesis routes, our team aims for a low-cost, straightforward approach. We are attempting direct C-S cyclization of dithienothiophene using inexpensive copper catalysts and exploring various sulfur sources, coordinating ligands, and solvents to identify the optimal conditions. Subsequently, we are synthesizing KHC01-04 via direct carbon-hydrogen aromatic cyclization using palladium and copper catalysts. Finally, we are applying these four organic small molecules as hole-transporting materials in inverted perovskite solar cells and investigating their photovoltaic properties. | en_US |
