1. Introduction The I–V characteristics of solar cells measured under dark and illuminated conditions provide an important tool for the assessment of their performance. The dark characteristics are the easiest way to estimate the quality of the junction and the grid and contact resistances.
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.
These techniques have been adequately modified, extended to cover the case of solar cells and used to extract the parameters of interest from experimental I-V characteristic of a Poly-Si solar cell under dark condition.
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.
The 2-diodes model is used to describe the dark I-V curves of the PV cell . (1) to a set of measured data using a nonlinear squares method of dark I-V measurement data. ... ... The current-voltage (I-V) curve for each component cell in the PV module is characterized by PV cell specific parameters' values.
Abstract: Dark current-voltage (I-V) curves are usually used to analyze the electric characteristics of solar cell device based on one-diode and two-diode equivalent circuit models. In this study, we extracted the parameters from dark I-V with Nelder-Mead algorithm and repeated error estimation method based on two-diode circuit model.
