Solar Cell for Pico Balloons. Polymer 4.8V 100mA

Ultra thin and light weight solar cells.
Nominal voltage 4.8V
One of these are needed to power my Pico transmitter but two can be used for extra power at very low solar angles .
The power reserve from the super caps will be about 10 to 30 seconds when using these.
The weight for a single solar cell is 3.38gram
 
These have a tendency to curl up so some bracing on the backside can be used to make it flatter. A thin 1mm carbon rod can be super-glued to the backside for this (not included)
A thin drinking straw can also be used when in a pinch.
