Photovoltaic Characterizations

Polarization and Mott Schottky plot

With the greenhouse effect and the increase of the price of the energy, new ways to produce energy are intensively developed. They include fuel cells, biofuel cells, nuclear, biomass, wind power, and photovoltaic. This note shows the contribution of the electrochemistry in energy fields – which is currently a hot topic – and discusses photovoltaic characterizations.

Among all these renewable energies, photovoltaic power seems very promising. Indeed, only 0.2% of the solar energy which touched the Earth surface will be sufficient to produce energy for all world [1,2]. A lot of work is performed in this field in order to improve the efficiency of such an energy supply.

This note shows the photovoltaic solar cells characterization by polarization and EIS techniques. These techniques allows the user to determine the cell performance (Isc, Eoc, PMAX, PT, FF) and model (equivalent circuit). Moreover, automatic fits on several EIS experiments are available in the “Z Fit” tool.
