The temperature of an oven is not enough, but a kiln is. You would want to acquire a scrap diffusion tube from a surplus place. There was someone who actually succeeded in making crude transistors and diodes at home, I believe. I don't remember who it was but Ms. Ellsworth ("circuitgirl") would probably remember - http://www.fatmanandcircuitgirl.com/ Mind you, it would cost thousands of dollars, and if you did make a solar cell, it would be more like a photodiode, likely far worse than a cuprous oxide cell you could make with a copper sheet, a hot plate, and salt. But like that kid that achieved fusion by plasma pinch in his basement, you'd get the bragging rights of saying that you did it.<br><b>References : </b><br> It is possible, but not easy.

Silicon doped at .001% is hopelessly contaminated. You would still have to form the oxide insulation layer, etch windows in it for contacts and vacuum-deposit ultrapure metal for electrical conduction. About the best you could manage in a home lab would be a simple diode.<br><b>References : </b><br>Five years laboring in the dungeons of the semiconductor industry. During that time we lost an entire fab line because somebody used a dry-chemical fire extinguisher and we couldn't clean the building adequately afterward.

But I would not advise doing it by hand, these materials at those temps can be very dangerous.<br><b>References : </b><br> That’s theoretically how it works.
