Abstract
The paper presents a set of numerical simulations performed in the frame of a two scales model development for a single-solar cell under AM0 standard solar spectrum. The charge transport and Poisson's equations in one dimension are solved in terms of electron density, hole density and electrostatic potential using a finite-element approach. The current density model considers both the diffusion in neutral regions and the drift within depletion layer. The calculations are done for equilibrium and under forward bias voltage. The aim of the numerical computations is to obtain the J-V curves and the conversion efficiency. The presented results of numerical simulations quantify the influence of the most important material parameters on the cell performances.
