A Better Approach To The Evaluation Of The Series Resistance Of Solar Cells
Abstract
Series resistance is an important parameter in solar cell design and fabrication. Methods reported in literature for its determination are not suitable for routine use. We describe a simple method for obtaining the series resistance. Universal current-voltage characteristics of the solar cells are also given to illustrate the effects of series and shunt resistance. We also offer an explanation for the often observed drop in efficiency when small area cells are scaled upward. Cells less than 0.25 cm* represent the intrinsic potential of any given structure or diode but do not reflect series resistance effects that must be eliminated with huger area cells and the practical problems of griding to allow for current collection.
