A Simple Approach For Determination Of Density Of States Distribution In An Organic Photoconductor
Published 2020 · Materials Science
Abstract An approach for the determination of the distribution of density of electronic states in organic photoconductors is proposed. It is based on the analysis of absorption coefficient spectral dependence and the photoconductivity temperature dependence of photosensitive thin solid films. Feasibility of the approach is demonstrated by a study of the dependences using co-polymer of phenylquinoline derivative and 2,1,3-benzothiadiazole as an organic photoconductor. The distributions of density of electronic states are described well by the Gaussian function, and the corresponding full-width at-half-maxima are determined.
