Experimental investigation of transient processes in single crystal Si solar cell panels

Three photo-voltaic commercial panels based on single crystal silicon solar cells are analyzed. Two types of transients are observed: an instantaneous short-circuiting and an instantaneous open-circuiting. It is shown that the transient currents under the short-circuiting has character of damped oscillations and the transient voltages under the open-circuiting rise exponentially for all types of solar cell panels. The results obtained cannot be explained by the currently used equivalent diagrams.
