The dark saturation current of a solar cell is 1.6E-8 A/m², the cell temperature is 391 K, the short-circuit current density is 185 A/m², Vmax is 0.516 V and the available solar radiation is 740 W/m2. The Boltzmann's gas constant is 1.381X10-23 J/K and the electronic charge is 1.602X10-19 J/V. Calculate Open-circuit voltage Voc in Volts = Current density at maximum power Imax in A/m²= Maximum power Pmax in W/m² = % Maximum efficiency nmax =
