Cells can be described as photovoltaic even when the light source is not necessarily sunlight (lamplight, artificial light, etc.) Photovoltaic cells are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
