Solar cell open circuit current is zero

Factors Controlling Open-Circuit Voltage Losses in Organic Solar Cells

The open-circuit voltage is the difference between the quasi-Fermi levels at the two contacts in an illuminated solar cell at zero current flow. Figure 2A, main text, shows a band diagram of a generic (organic or inorganic) thin-film solar cell at open circuit.When ...

Ideally, the current should be zero during the open circuit conditions. I don''t understand the source of this significant current in the open circuit condition. I have read plenty of literature mentioning the voltages to be not zero during short circuit condiitons and the need for the linear fit, but never read anything for the open circuit …

An equivalent circuit model of an ideal solar cell''s p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements. The resulting output current equals the photogenerated curr…
