Reflection: It is an
internal reflection within the cell itself. The light beam that gets into the
cell is being reflected back out. The photons that are being reflected back out
do not excite the electron and therefore don’t produce current, they are just
reflected back and out. The cell efficiency can be increased by minimizing the
amount of light being reflected away from the cell surface. Various
anti-reflection technologies help us to optimize light absorption. Most commonly
special coating is applied to the top layer of the cell. Better results, over a
wider range of wavelengths are possible with multiple antireflective layers.

Another way to reduce the reflection is to texture the top surface of the cell,
which causes light to be reflected back and forth within the cell until it is
completely absorbed.
