碩士 === 國立臺灣科技大學 === 化學工程系 === 102 === In this work, we have synthesized four new rubrene derivatives dye, TPTCA-R-tBu, TPTCA-L-tBu, TPTCA-OMe and TPTCA-CF3, and characterized by 1H NMR and mass spectrometry. Their HOMO and LUMO energy levels in solution and in solid state were estimated by differemtial pulse voltammetry, UV-visible absorption spectra, and low-energy photoelectron spectrometer, respectively. The electron distribution of molecules in excited state was investigated by density function theory calculation. Including DSSC testing, these results are compared with TPTCA. Under standard global air mass (AM) 1.5, the power conversion efficiency is using dip and drop methods of fabricating solar cells, the overall power conversion efficiencies of these solar cells by dip(drop) method are 6.15 %、4.68 %、4.46 %、4.33 % and 0.68 % (6.92 %、5.59 %、4.88 %、5.02 % and 1.14 % ) for TPTCA、TPTCA-R-tBu、TPTCA-L-tBu、TPTCA-OMe and TPTCA-CF3.
