Web(iv) Atomic Packing factor. Volume of all atoms in a unit cell(v) Atomic radius r = a/2. No of atoms per unit cell, n =6. Volume of all the six atoms in the unit cell. The volume of the unit cell of the HCP = base area x height. Thus the packing density is 74% and hence, it is a closed packed structure. Example. Zinc, Beryellium and Magnesium WebPacking Density. The packing density of solar cells in a PV module refers to the area of the module that is covered with solar cells compared to that which is blank. The packing density affects the output power of the module as well as its operating temperature. The packing density depends on the shape of the solar cells used.
