Résumé
The aim of this communication is to show that it is possible to extend the model of the electronic transport developed for amorphous silicon (a-Si:H) to microcrystalline silicon (μc-Si:H). By describing the electronic transport with the <i>μ</i><sup>0</sup><i>τ</i><sup>R</sup> products (mobility×recombination time) as a function of the Fermi level, we observed the same behaviour for both materials, indicating a similar type of recombination. Moreover, applying the normalised <i>μ</i><sup>0</sup><i>τ</i><sup>0</sup> product (mobility×life-time) obtained by combining the photoconductivity (<i>σ</i><sub>photo</sub>) and the ambipolar diffusion length (<i>L</i><sub>amb</sub>) measured in individual layers, we are able, as in the case of a-Si:H, to predict the quality of the solar cells incorporating these layers as the active < i > layer.
