本論文是使用溶液製程的方式,配合台大化學系汪根欉老師實驗團隊提供可以分別當作電子貢獻者以及電子接收者的有機小分子材料,探討正規結構下太陽能電池元件特性。
將有機小分子FTT與CTT分別當作電子貢獻者並搭配PCBM的情況下,光電轉換效率分別為2.23%和1.00% ; 然而FTT當作電子接收者並搭配P3HT的情況下,其光電轉換效率亦可以有0.69%,CTT則無效率。由薄膜的吸收光譜得知,FTT:PCBM 與 CTT:PCBM在CF溶劑中擁有相近的吸收度,但是,由外部量子效率可知FTT:PCBM 在所形成的主動層,其元件之光子轉換成電子的整體效率較CTT:PCBM來的好。並且,在原子力顯微影像當中,可以得知由FTT:PCBM的主動層相較於CTT:PCBM,有較低的表面粗糙度,所以可知FTT小分子搭配PCBM在CF溶劑下的溶解度較CTT佳,使得所形成的主動層表面輪廓較為平坦,進而影響主動層與電極之間的電荷傳遞特性,元件效率因此提升。

This thesis is to investigate the device properties of the organic small molecule used as the electron donor/acceptor materials, respectively, in solution process. The small molecules are provided by Prof. Ken-Tsung Wong in the department of chemistry in NTU.
The device efficiencies utilized the active layer of FTT:PCBM and CTT:PCBM are 2.23 % and 1.00 %, respectively. However, the device efficiency can still reach 0.69% with the active layer of P3HT:FTT. From the absorption spectra, both of the active layers (FTT:PCBM and CTT:PCBM) have the similar curves. But, for the measurement of external quantum efficiency (the efficiency of photons converted into electrons), the device with FTT:PCBM have better performance. Moreover, based on the AFM images,the morphology of the active layer consist of FTT:PCBM has the lower values of roughness compared to that of CTT:PCBM. This indicates the solubility of FTT:PCBM is better than that of CTT with the solvent of chloroform (CF), leading the smoother morphology of the active layer, improved the property of carrier transport ,and enhance the device performance.
