- Pronouncing it as 'photo-current' with equal stress on both parts (primary stress is on 'pho-').
FAQ
Frequently Asked Questions
Yes, essentially. The electricity a solar panel produces is a photocurrent, generated when photons from sunlight knock electrons loose in the panel's semiconductor material.
No, by definition, a photocurrent requires light. The small current that might flow in a device in the dark is called the 'dark current'.
No, it is a highly specialised technical term used almost exclusively in physics, engineering, and related scientific fields.
The photovoltaic effect is the physical *process* (creation of voltage and current from light). The photocurrent is the *result* – the measurable electric current that flows because of that process.
An electric current produced directly by the action of light, especially within a photoelectric or photovoltaic device.
Photocurrent is usually technical / scientific in register.
Photocurrent: in British English it is pronounced /ˈfəʊ.təʊˌkʌ.rənt/, and in American English it is pronounced /ˈfoʊ.ɾoʊˌkɝː.ənt/. Tap the audio buttons above to hear it.

Mnemonic
Think: 'PHOTO' (light) + 'CURRENT' (flow of electricity). A PHOTOCURRENT is the electrical current that flows when LIGHT hits a material like a solar panel.
Conceptual Metaphor
Light as a pump: Photons 'pump' electrons, creating a flow of electricity.
