Admittance and impedance spectroscopy on Cu(In,Ga)Se2 solar cells
The present work reports some experimental results on the electrical properties of high efficiency ZnO/CdS/Cu(In,Ga)Se2 heterojunction solar cells. Admittance spectroscopy has been employed for characterisation of the bulk ... -
Comparative study of ZnCr2O4-K2CrO4 ceramic humidity sensor using computer controlled humidity measurement set-up
Kavasoğlu, Neşe; Kavasoğlu, Abdulkadir Sertap; Bayhan, M (Elsevier Science Sa, 2006)A home-made ZnCr2O4-KCrO4 ceramic humidity sensor was studied using a commercially available reference humidity sensor, SHT75 from Sensirion. The main advantages of our developed set-up for humidity measurements are low ... -
Exact analytical solution of the diode ideality factor of a pn junction device using Lambert W-function model
The paper presents a new analytical method for extracting the diode ideality factor of a p-n junction device using Lambert W-function model and the dark current-voltage data. The extracted values are found to be in good ... -
Investigation of temperature dependent dc current transport mechanism on Au/poly(4-vinyl phenol)/p-Si device
Kavasoğlu, Abdulkadir Sertap; Tozlu, Cem; Pakma, Osman; Kavasoğlu, Neşe; Özden, Şadan; Metin, Bengül; Oktik, Şener (Iop Publishing Ltd, 2009)In this study, temperature dependent current-voltage (I-V) measurements and investigation of the dc current transport mechanism of Au/poly(4-vinyl phenol)/p-Si device have been performed. While the series resistance value ... -
A new simulation model for inhomogeneous Au/n-GaN structure
Kavasoğlu, Neşe; Kavasoğlu, Abdulkadir Sertap; Metin, Bengül (Pleiades Publishing Inc, 2016)The larger the device area, the more difficult to carry on homogeneity during the fabrication and following treatments. Structural inhomogeneity may indicate themselves in variations in local electronic device parameters. ... -
Simulation for capacitance correction from Nyquist plot of complex impedance-voltage characteristics
Kavasoğlu, Abdulkadir Sertap; Kavasoğlu, Neşe; Oktik, Sener (Pergamon-Elsevier Science Ltd, 2008)The impression of series resistance on unipolar semiconductor device's capacitance-voltage spectrum is discussed by conventional impedance and admittance analysis, and it is shown that series resistance may cause large ... -
Tunnelling enhanced recombination in polycrystalline CdS/CdTe and CdS/Cu(In,Ga)Se-2 heterojunction solar cells
Bayhan, Habibe; Kavasoğlu, Abdulkadir Sertap (Pergamon-Elsevier Science Ltd, 2005)This article investigates the results of current-voltage measurements made at different temperatures on vacuum deposited ZnO/CdS/Cu(In,Ga)Se-2 and CdS/CdTe heterojunction solar cells. We propose that the current-voltage ...
