An
eqmvalent resistance clrcult of a solar cell which takes Into account all the sources of lmear resistance m a solar cell IS developed. Equations which will determme the resistance of the diffused layer of a solar cell are also developed assummg a constant gradient across the d&used layer. The equations for the total senes resistance of an n dnnenslonal solar cell are evolved where IZ represents the number of grids m the cell. The equations have been utilized m conjunction with experimentally determined values of the component resistances to predict the total series resistance of several cell types. Very good correlation was obtamed between the experlmentally measured total series resistance and the theoretically predicted total series resistance of these cells.

A new method is presented to evaluate the series resistance of a solar cell. The method not only takes into account the effects of light and temperature on the series resistance, but also takes the diode junction ideality factor as an output current dependent parameter such that the values of the re
It is well known that a moderate sheet resistance of the emitter layer of a solar cell can be modelled as a lumped series resistance. It has no influence on the open-circuit voltage and little influence on the short-circuit current. The lumped series resistance model enables the fill factor loss to
