how is solar electricity made

Can I buy silicon solar cells and only ride my solar panel insulating materials like plywood?
Photovoltaic electricity is becoming one of the best energy source alternarive today but still a little expensive. As regular home users and beginners electrice solar energy, I realize profitability. I understand that silicon is the material standard of solar cell that is just not be manufactured at home, so you should buy, but I can make my own solar panel made of any insulating material such as wood or plain painted GI sheet metal frame with soldiers? Can I use the car battery 12v and AVR as a charge controller and low cost as a bridge rectifier inverter?
Absolutley, just be sure to include diodes batteries do not drain to panels through the night and make sure everything is waterseal for obvious reasons,
