I am trying to make a solar charger for my cell phone. So would the black go to black an and red to red?(sounds like a stupid question, but just want to be sure.

I don't know if your question was answered or not. I can tell you that if you are using a solar panel without a charge controller, at the very least you should insert a diode on the panels output to prevent it from draining your battery when the light level drops or night falls.
