Carbazole-based small molecules for high open-circuit photovoltage in organic photovoltaic cells

碩士 === 東海大學 === 化學系 === 104 ===   A novel donor-π bridge-acceptor (D-π-A) organic small molecules of F1-F8 have been designed and synthesized, in which an electron-donating carbazole moiety with 4-tert-butyl phenyl (F1-F4) or 4-dodecyloxy phenyl (F5-F8) and electron-withdrawing moiety with four dif...

The compound F1-F8 as p-type materials with C60 and C70 as n-type materials to form p-n junction by vacuum-deposited in organic photovoltaic cells. Investigation of photophysical, electrochemical and photovoltaic properties have been studied in these dyes. Compound F2 had showed the best short circuit current 5.13 mA/cm2, and the compound F1 combined with C60 (1:1) achieved a high power conversion efficiency 2.48% and gain high open-circuit voltage of 1.01 V because of it possesses the lowest HOMO energy level in organic photovoltaic cells. We optimized and demonstrated the device performance, the highest power conversion efficiency 4.93% by using C70 (1:4) as acceptor in compound F1. CHANG,YUAN JAY 張源杰 2016 學位論文 ; thesis 119 zh-TW
