Introduction to Solar Cells
A solar cell generates maximum power at a point in between these two extremes known as maximum power point (MPP). At MPP, current (I MP) and voltage (V MP) are maximum in the solar cell. On an I-V curve, the MPP is located near the bend as shown in Fig. 1.4.

The problem is that the absolute values in your graph look completely wrong. If the graph is flipped upside down, and based at zero power, zero current and zero voltage, then the blue curve does indeed look like an I-V curve for a photovoltaic cell, and the orange curve looks like the corresponding power curve.
Effect of Light Intensity
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2.
