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.

To understand the operating principles underlying the solar cell, one has to study first the p–n junction diode. Solar cells are made of either homotype p–n junctions, heterotype junctions, or even multi-junction. The homotype is from the same material, whereas the heterotype is from two different materials. The operating principles are the same.
