Impedance Spectroscopy for the Characterization of the All-Carbon Graphene-Based Solar Cell
March 24, 2023
Abstract
In this work, front contacts for graphene-based solar cells are made by means of colloidal graphite instead of gold. The performance is characterized by exploiting impedance spectroscopy and is compared to the standard gold contact technology. Impedance data are analysed through equivalent circuit representation in terms of lumped parameters, suitable to describe the complex impedance in the frequency range considered in the experiments. Using this approach, capacitance−voltage of the considered graphene−silicon solar cell is found and the barrier height forming at the graphene−silicon interface is extracted.
