A simplified flashlamp technique for solar cell series resistance measurements
Abstract
It is shown that the effective series resistance of a solar cell can be measured easily and accurately by the following simple technique. Two successive pulses (about 1 ms) of equal intensity from a high intensity flashlamp are used to measure first the open-circuit voltage V sub oc and secondly the voltage V sub L across a small known series load resistance R sub L. It is shown that to excellent accuracy the series resistance can then be computed from the formula R sub s = R sub L(V sub oc/V sub L - 1). The technique offers the convenience that the cell does not require heat sinking and problems of temperature variation are obviated.
