This paper analyses in detail the issue of non-destructive testing of n+p silicon solar cells. Their extremely large junctions contain lots of defect regions which deteriorate the properties of the whole solar cells. In the present work, we carried out experiments and theoretical description for the bulk inhomogeneity of the samples qualification. We propose an equivalent circuit model for the current-voltage characteristics of forward biased n+p solar cells, too. The model takes into account leakage current, series resistance and different mechanisms of charge transport. Spread series resistance issue of a solar cell front contact has been discussed and experimentally demonstrated. The electrical model admits analytical solution using e.g. the Lambert W-function and it has been tested for some spices of a solar cell in forward direction. Last but not least we use obtained information for description of the samples noise behaviour and we suggest noise model containing flicker noise, shot noise and G-R noise variant.
