1. Combines the technologies
of crystalline silicon
& thin films.
2. How it works
A. Two high temperature strings
are pulled vertically through
a shallow silicon melt
still in molten state.
B. The silicon freezes between
the strings and produces
continous long sheets.
3. This technology yields over
twice as many solar cells
per pound of silicon as conventional
methods. This allows
for high packing density
A. Early experiments produced
15% solar cells on thin
100 micron wafers.
