Consider an array of two-series identical Si solar cells. Each solar cell is of 6'' diameter and I0 = 1e-11A, Isc = 0.0343A, Rsc = 1e-3, Rsh=10k, respectively. Draw an equivalent dc electrical circuit for an array and indicate all important parameters. Plot I(V) characteristics for cell #1 and cell #2 and an array if: a) each cell is illuminated uniformly with 1000W/m^2 b) cell #1 is illuminated by 1000W/m^2 and cell #2 is illuminated by 700W/m^2. Please analyze obtained results. Does the power if each cell is the same? Explain obtained results.
