I am new to electronics and I have a female USB PORT, a solar cell, a cell, a 2xAA holder and some wire. How do I connect it to each other so that the solar cell charges the batteries and then in turn give power to the USB port? The solar cell is a 6V 120mA. I just want to know. Thanks!

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Buy a LM78O5 Voltage Regulator, connect the solar panel to input. Now, the output... The USB has 4 conductors. The outer ones are the power. Connect them to the output of the IC.
