Introduction to Solar Cells
The creation and collection of light-generated carriers cause the flow of short-circuit current in a solar cell. The light-generated current and short-circuit current for an ideal solar are identical. Therefore, the largest current that may be extracted from a solar cell is the short-circuit current.
Effect of Illumination Intensity on Solar Cells Parameters
When solar cells are utilized for indoor applications or integrated into a building, they are generally exposed to variable irradiance intensity. The performance of a solar cell is influenced by this variation as its performance parameters, viz. open-circuit voltage (Voc), short-circuit current (Isc), fill factor (FF) and efficiency (η).
