Open Circuit Voltage
The short-circuit current density is the photocurrent generated by the solar cell, expressed in the form of the current density under zero external field (i.e., 0 V). The flow of the photogenerated carriers to the electrode primarily depends on the built-in field of the solar cell. The short-circuit current density can be estimated as [45]:

Solar cells are specified with two values - short circuit current (in your case 100mA), and open circuit voltage (in your case 6V). 100mA does not mean 100mAh, and the rating of the cell is definitely in mA not mAh (mAh
Shorting a solar panel
Re: Shorting a solar panel A short circuit does not have anywhere for the energy to go (nothing external to the panel gets hot, nothing is moved)--So, from what I can see, no energy is removed from the panel. There may be some sort of effect at the PN junction with current flow vs not--But I have not read anything one way or the other.

What happens if you short circuit a solar panel?
When you connect both ends of your panel and create a short circuit connection what ends up happening is the voltage across your solar cells become zero. Short circuit current is actually the largest amount of current that can be drawn out of your panel. So it’s quite important to measure it for safety purposes.

Short circuit current is a measure of how much current a solar panel produces without a load on it. But how do you work out the short circuit current and why is it even important?
Do solar panels have a short circuit current rating?
All solar panels come with a short circuit current rating. This is when the current in the solar panel is at its maximum and there is no voltage. In this case, there is no power coming from the solar panel because there is no voltage. To get power from a solar cell you need both current and voltage. Current (Amps) x Voltage (Volts) = Power (Watts)
