Open-circuit voltage is the voltage across the solar cell when there is no current flowing in the circuit. This means I = 0 in Eq. 3.6b (Fig. 3.4a). There is infinite resistance between the terminals of solar cell. It can be found from Eq. () by substituting I …
Ohm''s Law confusion -
$begingroup$ In the circuit you have shown, yes current does flow through the 1GOhm resistor. As to the broader question, "does Ohm''s Law apply when the resistance is infinite?", personally I''d waft that away by saying Ohm''s law only applies to circuits - an (ideal) battery standing on its own does not constitute a circuit - but there are …
