Reconsider Prob. 18 - 40E. What is the maximum conversion efficiency of this solar cell?
Prob. 18-40E
A solar cell has an open circuit voltage value of 0.60 V with a reverse saturation current density of Jo 5 4.11 3 1010 A/ft2.
(a) For a temperature of 75oF, determine the load voltage at which the power output is maximum.
(b) If the solar irradiation is 220 Btu/h·ft2, determine the efficiency of the solar cell at a load voltage of 0.56 V.
(c) Determine the cell area, in ft2, for a power output of 500 W at a load voltage of 0.56 V.
