Different types of solar cells reacts differently to:
1) light spectrum (colors)
2) intensity
3) temperature
and some solar cells last longer with less degradation than the others.
They also have different transformation efficiency.
When taking into all the factors above, CIS is the most rounded technology that promise to deliver.
About the graph:
Wavelengths we can see is from around 400nm (blue) to 800nm (deep red).
The black line (Sunlight spectrum) shows the range of lights receiving on earth.
CIS (in purple) has the widest response and good sensitivity to different "colors" of light.
Amorphous silicon (a-Si, in blue) is good when the lights constitute more UV (or with fluorescent light bulbs).
Crystalline silicon (c-Si, in pink) is good for red and near-infrared lights.
