Photovoltaic Properties of Poly(Triphenylamine-Thiazolo[5,4-d] Thiazole) Copolymer Dye in Bulk-Hetorojunction Organic Solar Cells
Olgun, Ugursoy; Gulfen, Mustafa; HIZALAN, Gonul; Çırpan, Ali; Toppare, Levent Kamil (2017-04-01)
In this study, the photovoltaic properties of poly(triphenylamine-thiazolo[5,4-d]thiazole) alternating copolymer dye in bulk heterojunction polymer solar cells were examined. The copolymer is a red colored dye material with high thermal stability, good solubility and low-band gap energy. The band gap energy of the polymer was determined as 1.36 eV. The conductivity of the polymer thin film was measured as 1.5x10(-5) S/cm. The polymer solar cells were fabricated using the different ratios of the blends of th...
Photoluminescence properties of Si nanocrystals embedded in SiO2 matrix
Seyhan, Ayşe; Turan, Raşit; Department of Physics (2010)
This thesis examines the luminescence properties of nanoscale silicon (Si) by using spectroscopic techniques. Since the development of new optical devices requires understanding light emission mechanism optical spectroscopy has become more important tool in the analysis of these structures. In this thesis, Si nanocrystals embedded in SiO2 matrix will be studied. Photoluminescence (PL) and Time-resolved photoluminescence spectroscopy (TRPL) have been used to detect the light emission in UV-Vis-NIR range. Exp...
Photoexcitation Dynamics in Films of C-60 and Zn Phthalocyanine with a Layered Nanostructure
Lane, Paul A.; Cunningham, Paul D.; Melinger, Joseph S.; Kushto, Gary P.; Esentürk, Okan; Heilweil, Edwin J. (2012-02-15)
We elucidate photoexcitation dynamics in C-60 and zinc phthalocyanine (ZnPc) from picoseconds to milliseconds by transient absorption and time-resolved terahertz spectroscopy. Autoionization of C-60 is a precursor to photocarrier generation. Decay of the terahertz signal is due to decreasing photocarrier mobility over the first 20 ps and thereafter reflects recombination dynamics. Singlet diffusion rates in C-60 are determined by modeling the rise of ground state bleaching of ZnPc absorption following C-60 ...
