119 (maximum up to 230 V) such that ammeter reads a value of about 500 mA. Note down the value of the current as short circuited current, I sc . 3. Increase the resistance by varying the rheostat slowly and note down the readings of current and voltage till a maximum voltage is read. Ensure to take at least 15 – 20 readings in this region. 4. Disconnect he rheostat and note down the voltage. This is the open circuit voltage, V oc . 5. Repeat the experiment for another intensity of the illumination source. 6. Tabulate all readings in Table 1. Calculate the power using the relation, P = V x I. 7. Plot I vs. V with I sc on the current axis at the zero volt position and Voc on the voltage axis at the zero current (see Figure 5.) 8. Identify the maximum power point P m on each plot. Calculate the series resistance of the solar cell using the formula as follows : R S = [ Δ V/ Δ I ]. 9. To see the performance of the cell calculate fill factor (FT) of the cell, which can
