The next in our series of small-scale, high voltage solar cells is the SCC3766. Nominally rated at 6.7V and 30mA, our direct-sunlight tests show just over 8V open-circuit, and 44mA short-circuit!

Epoxy protects the 14 cells mounted on a PCB backplane, making these very robust. You won't risk breaking these like the old glass-backed cells.

These new cells also feature a SOT123 footprint on the backside for installing a user supplied parallel-wired zener diode for over-voltage protection.
