Typical solar cell output characteristics are illustrated in Fig. 20-25. Consider the characteristic for a 100 mW/cm 2 illumination level. If the cell is short-circuited, the output current (I o) is 50 mA cause the cell voltage (V o) is zero at this point, the output power (P o) is zero.. Open-circuiting the cell gives V o ≈ 0.55 V, but I o = O. So, P o is again zero.
