Q.

Consider a silicon p-n junction solar cell of area 4 cm2. If the doping of the solar cell are NA = 1.0x1016cm-3 and ND = 1.5x1019 cm-3 and given τn = 10 μs, τp = 0.5 μs, Dn = 9.3 cm2 /s, Dp = 2.5 cm2 /s and IL = 95 mA, (a) calculate and plot the I-V characteristics of the solar cell, (b) calculate the open-circuit voltage and (c) determine the maximum output power of the solar cell, all at room temperature.

Expert Solution

The solar cell is a p-n junction diode that transforms sunlight to electricity with a large conversion efficiency. When light falls on the diode, photons are absorbed and electron-hole pairs are produced in the p and n regions.
