A photo voltaic cell generates an open circuit voltage of 0.72 V and a short circuit current of 350 mA whenmiated by light wi ketch the V-I characteristic of the cell under these conditions. Estimate the open circuit voltage and the short circuit current when illuminated by a light with power density of 600 Wm 8. ith power density 1000 Wms 3. The polarization curve for a fuel ce is shown in Figure 1 1.5 1.0 0.5 0.5 current density A em Figure 1 Complete the following table to determine the maximum power density (W/cm) Calculate the efficiency at this operating condition Voltage Power Densit W/cm 0.75 1.00 Current Densit A/cm 0.75 0.66
