Under the 1-sun condition, a 0.005m² PV cell has short circuit current Isc = 6A and reverse saturation current lo = 5 X 10-10 A. Equivalent circuit of the PV cell includes a parallel resistance (Rp) of 70, a series resistance (Rs) of 1m and a diode with junction voltage (V.) of 0.57 V. PV cell's junction temperature is T = 27°C. Constants and Conversion Factors - Boltzmann Constant K = 1.381 x 10-23 J/K. Electron Charge q = 1.6 x 10-19 C. Conversion → [Temperature] in °C = [Temperature + 273] K a. Draw the equivalent circuit of the PV cell. Draw and Label all the circuit elements, voltages, and currents properly to get full point. [5] b. Find the voltage, current and power delivered by the PV cell under the above conditions. [5] C. A PV module is made up of 72 such identical cells wired in series. Find the total voltage, current, and power delivered by the PV module. [5] d. In addition to the total PV area, 'Casing of the PV Module' and 'Spacing between PV Cells' is covering additional 0.075m² in total. What is the overall efficiency of PV module? [5] e. If one cell in the 72 cell module in (c) is shaded and the current in string somehow stays the same, what would be the effective module output voltage, current and power? [5] Calculate the power dissipated across the shaded cell the new efficiency of PV module. [5] Ans: Power dissipated= 118.2 W g. Draw I-V curves for the shaded module of part (d) in the following graph. Use proper scaling to draw the graph. Calculate and label the values properly to get full points. [5] f.
