Abstract
In this paper graphene on silicon solar cells, adopting either gold contacts or graphite contacts, are characterized by means of the impedance spectroscopy analysis. Experiments are described in terms of equivalent circuit model, and lumped parameters allowing to reproduce experiments in the whole set of frequency and dc biases are given. From this analysis the C-V plot of the solar cell is extracted, and the barrier height of the graphene-silicon interface is derived.| File | Dimensione | Formato | |
