Customer ServiceDark current is one of the main sources for noise in image sensors such as charge-coupled devices. The pattern of different dark currents can result in a fixed-pattern noise; dark frame subtraction can remove an estimate of the mean fixed pattern, but there still remains a temporal noise, because the dark current itself has a shot noise.

Customer ServiceConferences > Conference Record of the Twen... Dark current-voltage (dark I-V) measurements are commonly used to analyze the electrical characteristics of solar cells, providing an effective way to determine fundamental performance parameters without the need for a solar simulator.
Dark current-voltage (I-V) response determines electrical performance of the solar cell by providing reliable and accurate information regarding its series and shunt resistances, diode factor, and diode saturation currents; the diode parameters determine the quality of metallization and solar cell efficiency.
The use of Dark IV curves in solar cell analysis relies on the principle of superposition. That is, in the absence of resistive effects, that the light IV curve is the dark IV curve shifted by the light generated current. While this is true for most cells it is not always the case.
An additional way to evaluate the performance of a PV device through the dark I-V curve is by obtaining the parameters of the dark curve equivalent to the illuminated one by transposing the dark I-V curve to the short circuit current of the illuminated one and calculating the fill factor dark (FFD) [31, 34, 35].
Since solar cells convert light to electricity it might seem odd to measure the photovoltaic cells in the dark. However, dark IV measurements are invaluable in examining the diode properties. Under illumination, small fluctuations in the light intensity add considerable noise to the system making it difficult to reproduce.
The dark I-V measurement procedure does not provide information regarding short-circuit current, but is more sensitive than light I-V measurements in determining the other parameters (series resistance, shunt resistance, diode factor and diode saturation currents) that dictate the electrical performance of a photovoltaic device.
