Polycrystalline (or Multicrystalline) 

Polycrystalline (or Multicrystalline) cells are effectively a slice cut from a block of silicon, consisting of a large number of crystals.
They have a speckled reflective appearance and again you can you see the thickness of the slice. These cells are slightly less efficient and slightly less expensive than monocrystalline cells and again need to be mounted in a rigid frame.
