24 x 33mm Polycrystalline Solar Cell
The SCC2433-B solar cell is a monocrystalline cell offering 4.5V (open circuit) and 18mA (short circuit) in a 24x33mm package.
What really makes this solar cell stand out is the circuit board on the back! It lets you assemble the simple "Miller Solarengine" which lets you pulse-power devices that would usually be impossible to power!
The Miller Solarengine is pretty well described "Bicore Experimenter's PCB" series of circuits.
