Consider a 100-cm² photovoltaic cell with reverse saturation current I0 = 10-12 A/cm² . In full sun,nit produces a short-circuit current of 40 mA/cm² at 250 C. Find the open-circuit voltage at full sun and again for 50% sunlight. Plot the results (I vs V).

4. For the unity feedback system shown in Figure, where R(s) E(s) G(s) C(s) G(s) = 450(s+8)(s +12) (s +15) s(s+38) (s+2s +28) find the steady-state errors for the following test inputs: 25 u(t), 31tu{t), 47tu(t).
