The primary characteristics of a solar cell can be determined by using an I-V curve to examine the relationship between the current and voltage produced. Current level is determined by the intensity of solar radiation on the cell, while
State-of-the-art solar cell technologies, such as hetero-junction cells or PERC cells, exhibit a time-dependent deformation of their current-voltage characteristics in fast solar simulator measurements. This hysteresis effect is due to an increased internal capacitance. It manifests itself as a pronounced difference between I–V-curves depending on the
The exact measurement of area of a solar cell is also open to debate, but for now we''ll leave those details to others. Standardized Tests of Solar Cells Because there is a great deal of work both commercial and academic in the field of photovoltaics, there is also a great need for standardization of the methods and means of comparing one device to another.
