How Does High Dark Current Impact Solar Cell Performance?

I know how dark current is produced, but what if its high and how does it affect, say solar cell?

Ironic user name, eh?

What can you tell us about dark current? What have you read about it so far? Is dark current good or bad in solar cell operation?

Is dark current anything like the black oil on the "X-Files"?

It’s a relatively small electric current that flows through a photosensitive device when no photons are entering the device.

How does it affect the device when its high?

Which direction does the dark current flow? In the same direction as the photocurrent, or opposite?


EDIT -- Even more to the point, Google this for some helpful articles -- photovoltaic cell dark current
