The circuit below feeds a control current and voltage of a lithium ion battery 3.6v. The current is limited to 300 mA and the voltage is limited to 4.2 volts. The circuit uses a LTC1734 IC from Linear Technology. No diode is needed between the circuit and a 6-volt solar panel.

Some very nice 6-volt solar panels are available in http://www.plastecs.com Su-SP6 200-12 rods about 1 watt, while the Service Pack 6-300-12 can produce about 2 watts. Assuming that a sunny day, 6 hours, 2-watt panel will pump about 1.8 amp-hour battery.
