For the voltage you just need to use a 7805 regulator (You can buy it in a Radio Shack or something like that) to drop down any voltage between 6 and 12 volts to 5. The pin at the left is the input,  the one in the middle is the ground and the one at the right is the output. You just need to connect the positive wire (Red) of the solar panel at the left and the negative (Black) of the solar panel at the middle. Then for the USB cable you just need to connect the black wire at the middle and the red at the right. For the iPhone you will need to connect the red wire (Positive) with the white and the green one (Data) to make sure it charge (It worked with my iPod touch so it will work with a iPhone too. It worked for me (https://www.instructables.com/id/Convert-a-generic-dynamo-flashlight-into-an-AA-bat/).
