Electro-Analytical Method for the quantities evaluation of the silicon solar cell by DC and AC characterization technique
Materials Research Bulletin, 2018Co-Authors: Kavita Pandey, Dhyey Raval, Abul Kalam, Manjeet Kumar, Manoj Kumar, Joondong Kim, Pankaj YadavAbstract:Abstract Mono and Poly- crystalline silicon (Si) based solar cell has proven to be the most efficient and matured technology till date. The present work reports an exact Electro-Analytical Method for the evaluation of different performance parameters in the current voltage response of the Si solar cell by DC and AC characterization technique. The extracted solar cell parameters from DC and AC techniques were compared with each other under the proper limiting conditions of low and high forward bias. The DC and AC characterization are used to determine the bias dependence of ideality factor and series resistance, respectively. The current-voltage (J-V) characteristics is combined with the impedance spectroscopy (IS) measurements to reveal the various interfacial, resistive and recombination analysis of the silicon solar cell. Herein the experimentally obtained J-V characteristics under the illumination condition have been reconstructed by individually extracted parameters from DC and AC measurements. Moreover, the present mechanistic provides a simple tool for analysing the commercial Si solar cell with a wide applicability for other solar cells.

Comparison of D.C. and A.C. Electro-Analytical Methods for measuring diode ideality factors and series resistances of silicon solar cells
Current Applied Physics, 2013Co-Authors: D.j. Crain, S.e. Rock, J.e. Garland, Dipankar RoyAbstract:Abstract The diode ideality factor ( m ) and the series resistance ( R s ) of a Si solar cell represent two critical performance-indicator parameters of the device. Since both m and R s are functions of voltage ( V ) and temperature ( T ), simultaneous electrical measurements of these parameters under variable conditions of V and T can often be difficult with traditional direct current (D.C.) techniques. Using the Electro-Analytical Method of linear sweep voltammetry (LSV) and a commonly available Si solar cell, we explore these specific confines of such D.C. measurements. The results are compared with those obtained from a parallel set of alternating current (A.C.) measurements using impedance spectroscopy (IS). LSV provides the main D.C. parameters (open circuit voltage, short circuit current, fill factor, and efficiency) of the cell, but is limited in terms of independently measuring m and R s beyond strong forward biased conditions. The IS approach is free of the latter experimental constraints, and at the same time can provide several other important electrical parameters of the solar cell. Specifically, IS detects the presence of a low-high (p–p + ) junction at the back surface of the cell, and serves as an efficient probe of certain electrical characteristics of this junction.
