Abstract
Multicrystalline silicon structure and its effect on solar
cell efficiency have been studied. Multi-silicon wafers
have been found to differ only in the fraction of small
grains sized up to 2—4 mm whereas the medium
and large grain fractions are approximately constant.
A wafer sorting method by multicrystalline silicon grain
size which includes a quantitative measure has been
discussed. High content of the small grain fraction can
reduce solar sell efficiency.
