GaAsN as a photovoltaic material : photoelectrical characterization

In summary, we present in this study the results of studies on the layers of GaAs1-xNx grown on n-type GaAs substrates by atmospheric pressure metal organic vapour phase epitaxy (APMOVPE), Using transmittance, reflectance, photocurrent measurements and empirical expression for Eg a new nitrogen content for the studies samples was obtained. Using dark and illuminated I-V characteristics the main parameters of the Schottky contacts (short-circuit current Isc, open circuit-voltage, Voc, and fill factor, FF) were determined. Obtained contacts are promising for solar cell application.
