What Should I Wear On A First Date Ice Skating

classic photovoltaic cells (Si) amorphous or crystalline. (Then in another post we will see how to make homemade photovoltaic cells with other systems, for those who want to investigate solar power.)

What follows comes from a comment found on the web:

The manufacture of wafers If an industrial process rather expensive, I doubt q can be performed in a laboratory.
is necessary to melt the Si from sand or other materials and obtain much higher purity than 99%. Then it is necessary to crystallize
q If molds that can withstand very many temperature to monocrystalline cylindrical mold is required and a "seed" with the atomic configuration viewed, and to amorphous and polycrystalline is "a little" easier. With the silicon crystals are obtained at q is called a billet. Q
This billet is cut into very thin wafers with laser procedures or diamond saw very latest technology.
These wafers are the basis of any electronic component, and must be doparlas with elements such as boron or phosphorus at high temperatures and pressures to make semiconductor. For a solar cell wafer is doped q by a unique PN junction homogeneous throughout the cell, and distribute a metal mesh on both sides to capture the electrons q occur.
do not know if you have to do, but as I said mut process is expensive and it is true that there are very few companies that make the whole process.
