Question

How are solar panels made and what materials and chemicals are used?

Answer 1

You can make a solar water heater, with an old flat radiator, painted mat black and placed in a glass frame, perhaps double glassed. With insulation and reflecting foil behind. Then connected appropriately to the water system.

Answer 2

mono/poly crystalline or silicon amorphous, some have thin glass over thin mirror and beneath those layer are cells that hold the mono poly crystalline and silicon amorphous.

Answer 3

Photovoltaic? It requires a large factory with special equipment and chemicals to do this.

If you mean solar concentrators for hot water heating, then you need lots of copper tubing, glass, aluminum foil...
