Using the data in the spreadsheet "graded HW1 diodes". The photodiode/solar cell area is 3 x 3 sq mm. Illumination intensity= 75 W/cm Show the calculations and compile your plots in ppt for all the questions. Remember to label axes, show legends, and explain what you did. Support your claims based on the plots. (2 points for each question) 1. Show the current density (A/cm) versus applied voltage of the diode in dark and under light, in log and linear scale (y-axis). 2. Calculate and plot power versus voltage. Power is the product of current density*voltage. 3. Report the short-circuit current density, open-circuit voltage Jsc Voc 4. Report the power conversion efficiency. Show the relevant values you used in the calculation. 5. A student got the following plot by accidentally switching the polarity of the electrodes. What is different with this plot from your #1 answer, and indicate the diode polarity with respect to the applied voltage. current-voltage characteristics Current density [A/cm^2] 1.E-04 0.E+00 -1.E-04 -2.E-04 -3.E-04 -4.E-04 -5.E-04 -2 -1 0 Voltage [V] 2 D 1 2 B 4 5 5 7 3 3 D 1 2 B 4 5 5 7 B 9 D 1 2 B 4 5 5 7 3 9 Illumination wavelength: 480 nm-630 nm (white LED light) Illumination intensity: about 75 W/cm^2 PCE10 device,0.09 cm^2 Voltage (V) Dark current (A) -1.6 -1.5 -1.4 -1.3 -1.2 -1.1 -1 -0.9 -0.8 -0.7 -0.6 -0.5 -0.4 -0.3 -0.2 -0.1 0 0.1 0.2 0.3 0.4 OOOOOOOOO 0.5 0.6 0.7 io 00 0.8 0.9 1 1.1 1.2 1.3 1.4 1.5 1.6 -5.68E-08 -5.04E-08 -4.58E-08 -4.06E-08 -3.60E-08 -3.16E-08 -2.74E-08 -2.38E-08 -2.01E-08 -1.69E-08 -1.36E-08 -1.05E-08 -7.89E-09 -4.91E-09 -3.10E-09 -2.22E-09 -6.05E-10 1.61E-09 4.63E-09 8.62E-09 1.65E-08 4.03E-08 1.07E-07 9.25E-07 6.16E-06 2.15E-05 4.48E-05 7.85E-05 1.28E-04 1.81E-04 2.64E-04 3.57E-04 4.52E-04 Illumination current (A) -1.49E-06 -1.46E-06 -1.43E-06 -1.40E-06 -1.38E-06 -1.35E-06 -1.32E-06 -1.29E-06 -1.26E-06 -1.23E-06 -1.20E-06 -1.17E-06 -1.14E-06 -1.12E-06 -1.09E-06 -1.06E-06 -1.03E-06 -1.00E-06 -9.61E-07 -9.14E-07 -8.61E-07 -7.55E-07 -5.64E-07 5.69E-07 6.51E-06 2.24E-05 4.61E-05 7.98E-05 1.30E-04 1.82E-04 2.65E-04 3.58E-04 4.53E-04
