Help me with choosing proper diode for my solar panel battery charger Answered

I am have two of these solar panels:
http://www.flexsolarcells.com/index_files/OEM_Components/Flex_Cells/pages/Flex_Cells_Individual_06_SP42_37.php

Voltage4.2 V
Current22 mA
Voltage (oc)5.9 V
Current (sc)30 mA

I have connected the two in parallel for more current. I am making a charger for 3.7V mobile battery. What would be the most appropriate diode to use?

Thanks for your help.

. Look for a diode that will handle 60mA or greater and has a low forward voltage drop (eg, Schottky diode ).

and presumably a high breakdown voltage
