Abstract:	隨著對能源的需求越來越大，太陽能電池是科學家們致力研究的方向之一，近年來，因鈣鈦礦太陽能電池的大幅度成長而備受矚目，因此本論文合成鈣鈦礦電池之電洞傳輸材料，並探討材料性質與元件效率。論文分為兩個部分，第一部分是合成含硒的電洞傳輸材料，並改變硒氧雙鍵的數目，增加分子內電荷傳輸能力，也提高元件的電洞傳輸能力。第二部分則是設計並合成含 CONH 官能基的小分子 D-A 型電洞傳輸材料，透過CONH官能基中氮上面的氫產生分子間作用力，優化電洞傳輸材料的成膜性質；另外，氮上面的氫能與鈣鈦礦中的鹵素原子有交互作用力，達到鈍化缺陷的目的；最重要的是，使用浸泡的方式塗布在 ITO 上，藉由 CONH官能基enolate 形式與ITO 導電玻璃產生化學作用力，使其成膜更為平均，並且因浸泡方法未來可以做大面積的塗佈，因此商業價值提高。;Nowadays, scientists work on solar cells because of the increasing demand for energy. And the rapid growth of perovskite solar cells is high profile. I study hole transport materials and discuss material properties and device efficiency. There are two parts in my thesis, the first part is synthesis of selenide, selenoxide and selenone hole transport materials to increase intermolecular charge transport ability and improve the hole mobility of the device. The second part is studies of thiophenes with the CONH chelating groups as the D-A type hole transport materials. Through the hydrogen of the CONH group generating intermolecular effect to enhance the film-forming properties of the hole transport materials. And there is also passivation effect between hydrogen and the halogen atoms in the perovskite. Last, there is a chelating interaction between the CONH groups and the ITO glass. While HTMs chelating to ITO glass, successfully enhancing the film property and improving the efficiency.
