making your own solar cell's

Off hand, no - unless you plan to make thousands of them. But one never knows....

Still, it never hurts to have a source for potential companies. Check out http://www.solarbuzz.com/ for names of companies that are starting up. Recent developments have seen a cost drop from $4 per watt to $1 per watt. There are opportunities on both ends of that scale.

You can order as little as 12 5"x5" solar cells for $4 per cell at http://www.solarphotovoltaiccells.net. I hope this helps, and good luck with your solar panel building.
