1. Developed in 1981
2. Single
cell modules are created by cutting
cells from a continous crystal
3.
Polycrystalline are similar except that instead
of being cut from a monocyrstalline
structure they pour the the
crystal matrix into a mold. this creates
a square block that creates less
waste of space and is actually less
efficient in utilizing solar energy
than single cells, but is greater per
watt than single cell modules.
4. When the
mold cools it creates random
crystals that look pressed together and
have different variations of
blue.
