We report on the photophysical properties and photovoltaic performance of a polythiophene derivative, poly-2,3-bis(4-tert-butylphenyl)-5,8-bis(4-hexylthiophen-2-yl)quinoxaline(PHTQ) as an electron donor in bulk heterojunction Solar Cells blended with the acceptor 1-(3-met hoxycarbonyl)propyl-1-phenyl-[6,6]-methanofullerence (PCBM). Devices were composed of PHTQ and varying amounts of PCBM (1:1, 1:2, 1:3, 1:4 w-w ratio). The components were spin cast from ortho-dichlorobenzene (ODCB) and characterized by measuring current-voltage characteristics under simulated AM 1.5 conditions. Efficiencies up to 0.3% have been reached. Incident photon to current efficiency (IPCE) is reported and the nanoscale morphology was investigated with atomic force microscopy (AFM). Photoinduced absorption spectroscopy confirms the photoinduced charge transfer in such donor acceptor blends.

Experimental insight into the performance characteristics of Ni-mesh semiconductor photo-electrochemical cells Bayer, I; Eroğlu, İnci; Turker, L (Elsevier BV, 2000-04-15) The performance characteristics of two photo-electrochemical cells with different cell configurations were investigated at 25 degrees C and within the illumination range of 70-100 W/m(2). These cells included a jacketed single cell (JSC) and a jacketed two-compartment cell (JTC). Ni-mesh was used as a counter electrode and as a backing material for semiconductor electrodes. Semiconductor electrodes were prepared by silk-screen painting technique using TiO2, WO3, PbO, Sb2S3, ZnO, Al2O3 or CuO powder mixed wi...
Relative Photon-to-Carrier Efficiencies of Alternating Nanolayers of Zinc Phthalocyanine and C-60 Films Assessed by Time-Resolved Terahertz Spectroscopy Esentürk, Okan; Lane, Paul A.; Heilweil, Edwin J. (American Chemical Society (ACS), 2009-10-29) Multilayer and 1:1 blended films of zinc phthalocyanine (ZnPc) and buckminsterfullerene (C-60) were investigated as model active layers for solar cells by time-resolved terahertz spectroscopy (TRTS). Relative photon-to-carrier efficiencies were determined from ultrafast decay dynamics of photogenerated carriers using 400 and 800 nm excitation for delay times up to 0.5 ns. The findings are in good agreement with reported solar-cell device measurements, and the results exhibit a near linear increase of the re...
TEMPERATURE-DEPENDENT ELECTRICAL CHARACTERISTICS OF AL-SIOX-PSI SOLAR-CELLS OZDEMIR, S; ALTINDAL, S (Elsevier BV, 1994-02-01) Current-voltage (I-V) and capacitance-voltage (C-V) characteristics of Al-SiOx-pSi metal-insulator-semiconductor (MIS) solar cells were measured in the temperature range between 295 K and 375 K. The semilogarithmic plot of the dark forward current-voltage curves were found to be linear and the slope was almost independent of temperature in the intermediate voltage region. Consequently, the diode quality factor was strongly temperature dependent changing linearly with inverse temperature. A decrease in the z...
On the application of hole-selective MoOx as full-area rear contact for industrial scale p-type c-Si solar cells Nasser, Hisham; Es, Fırat; Zolfaghari Borra, Mona; Semiz, Emel; Kokbudak, Gamze; Orhan, Efe; Turan, Raşit (Wiley, 2020-11-01) We present the feasibility of integrating substoichiometric molybdenum oxide (MoOx) as hole-selective rear contact into the production sequence of industrial scale p-type crystalline silicon (c-Si) solar cells. Thin films of MoOx are deposited directly on p-type c-Si by thermal evaporation at room temperature. It is found that Ag/MoOx/p-type c-Si rear contact structure exhibits low contact resistivity and modest surface recombination current density. The attained peak efficiency (eta) of the fabricated sola...
Refractive index, static dielectric constant, energy band gap and oscillator parameters of Ga2SeS single crystals Qasrawi, A. F.; Hasanlı, Nızamı (Wiley, 2007-09-01) The optical properties of Bridgman method grown Ga2SeS crystals have been investigated by means of room-temperature transmittance and reflectance spectral analysis. The optical data have revealed direct and indirect allowed transition band gaps of 2.49 and 2.10 eV, respectively. The room-temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as...
