Unformatted text preview: Calculate the series resistance and fill factor. Results: 1. The I-V characteristic was drawn for given solar cell for two illumination levels. 2. The open circuit voltages and short circuit currents for two different illuminations are measured as : V oc1 = ___________;V oc2 = ____________; I sc1 = _____________ and I sc2 = ____________ 3. The series resistance of the cell calculated using the two plots is ______________________. 4. Fill factor : (One graph paper required) ....
