. a solar photovoltaic cell is designed to operate at maximum efficiency under a load of 0.4 a and 0.52 v under 750 w/m2 of irradiation at 45 degc. if the cells reverse saturation current density is 5.8x10-9 5a/m2 and the cell surface area is 0.01 m2 , what is the cells open circuit voltage (in volts) and short circuit current (in amps)?
