Cell phone and “small radio” are two different things. Actually, you don’t want to charge either one of those things, you want to charge their batteries.
Charging modern batteries is somewhat of a black art. If you want to charge the battery in your cell phone, I would strongly reccomend that you use the charger that came with it. If it came with a “car charger,” great! You can use a nominal “12V” solar array to power the charger, and use the charger to charge the phone’s battery.
If you just try hooking up solar cells directly to your cell phone, and you don’t know the detailed specifications of the phone and its battery, then your likely outcomes range anywhere from “nothing happens” to “the battery catches fire or explodes.”
If you google for “solar charger” you will find a variety of ready-made solar products into which you can safely plug your cell phone’s car charger.
