Abstract:
|
An analytical expression for the voltage dependence of the internal collection efficiency of amorphous silicon p-i-n solar cells is presented. The influence of arbitrary drift lengths (asymmetrical case) is taken into account and it is shown how this asymmetry affects the spectral dependence of the collection. A new experimental technique is proposed to determine the so-called collection voltage. Comparison between preliminary experimental data and theoretical results reveals the limitations of the analytical description. |
