This article will let you know how
to make a sun powered cell at home, and subsequent to making this you can

Take a copper sheet and cut it into
equal parts. After cutting you have 2 pieces of
the same size.
Heat up one piece of copper sheet
completely using a burner or gas stove.
Heat up 20 to 30 minutes. Then place it undisturbed to cool down
Attach a piece of copper wire to it. Clear that place where you will attach copper wire to it.
Take another piece of copper sheet
and attach it to another piece of copper wire.
Take a plastic bottle and cut it
half. In the bottom part of bottle make a
solution of hot water and salt.
Paste burned copper sheet in the
bottle. Only copper sheet touched with
water not copper wire.
In opposite direction paste another
piece of copper sheet.
Now your solar cell is ready to be
attached to anything to the wire which is attached to copper sheets.
