    本計畫希望可以合成一系列可應用於塗佈製成的共軛小分子，並探討分子結構對有太陽能電池的效率影響。我們將以文獻高效率小分子(DR3TBDTT)為基礎，利用我們提出的幾個常見的推 電子單元，以及自行設計的拉電子單元，對此高效率小分子進行改良，希望可能建立起對分子能隙與能階調控的能力，讓分子能更有效的吸收太陽光並且與碳球有適當的能階差。另一方面， 我們將對改變小分子上長碳鏈的位置或是數目，研究側鏈修飾在分子堆疊與排列上的影響，期望可以建立對DR3TBDTT系列小分子的晶體形貌的操控能力。最後我們將結合元件，測試計 畫中和成的小分子其光伏元件特性，利用同步光源與電子顯微鏡等設備，分析分子在主動層中的排列與相分離，並整理出調控最佳主動層形貌的方法。

    In this study, we have strategically designed and convergently synthesized two novel, symmetrical, and linear A-D-A-type pi-conjugated donor molecules (TBDTCNR, TBDTCN), each containing a planar electron-rich 2-octylthiene-5-yl-substituted benzodithiophene (TBDT) unit as the core, flanked by octylthiophene units and end-capped with electron-deficient cyanoacetate (CNR) or dicyanovinyl (CN) units. We thoroughly characterized both of these materials and investigated the effects of the end groups (CNR, CN) on their optical, electrochemical, morphological, and photovoltaic properties. We then fabricated solution-processed bulk heterojunction organic solar cells incorporating TBDTCNR and TBDTCN. Among our tested devices, the one containing TBDTCNR and [6,6]-phenyl-C-61-butyric acid methyl ester in a 1:0.40 ratio (w/w) exhibited the highest power conversion efficiency (5.42%) with a short-circuit current density (J(sc)) of 9.08 mA cm(-2), an open circuit voltage (V-oc) of 0.90 V, and an impressive fill factor (FF) of 0.66 under AM 1.5G irradiation (100 mW cm(-2)). The FFs of these solution-processed small-molecule organic solar cells (SMOSCs) are outstanding when compared with those recently reported for benzodithiophene (BDT)-based SMOSCs, because of the high crystallinity and excellent stacking properties of the TBDT-based compounds.
