Abstract

In this work we present a method to evaluate the short-circuit photocurrent density delivered by a solar cell by and study basic parameters which are at the origin of the latter by considering the solar spectra AM0, AM1 and AM1.5. This photocurrent density is the greatest current density that the cell can supply according to the considered parameters for a given illumination. We apply this method to a 4-layer model composed of absorber materials based on chalcopyrite semiconductors (CuInSe₂ and CuInS₂) and based on a wide band gap window layers (ZnO and CdS) according to the model ZnO(n⁺)/CdS(n)/CuInS₂(p)/CuInSe₂ (p⁺) (model n⁺/n /p/p⁺). For this model the CuInS₂ and CuInSe₂ layers are named respectively base and substrate. We exploit continuity equation that governing charge carriers transport in semiconductor materials and use Newton's quadrature integration method over the entire solar spectrum ranging from 1 eV to 4 eV. For this calculation, we have found values of the short-circuit photocurrent density equal to 24.5 mA.cm^-2, 19.3 mA.cm^-2, 17.5 mAcm^-2 respectively for the spectra AM0, AM1 and AM1.5 for the used parameters. The same principle of calculation and reasoning is used to determine and study under a given solar spectrum some intrinsic basic parameters such as the generation rate of carriers, the densities of minority carriers generated and the resulting photocurrents versus the junction depth. The study of these parameters shows a low penetration depth of photons for the considered materials CuInS₂/CuInSe₂, losses of charge carriers due to recombination phenomena in surface and interface, bulk recombinations, and losses which are also due to the natural phenomenon of diffusion of carriers in the material under a concentration gradient. This study tries to show that the optimization of the growth conditions of layers, a good choice of material arrangement and a good geometric dimensioning are essential to improve collection efficiency of charge carriers and the short-circuit photocurrent of a photovoltaic cell.
