Characterization of Photovoltaic Devices by Spectroscopic Ellipsometry

Much of solar cell research is focused on making solar cells cheaper and more efficient, so that they can more effectively compete with other energy sources. Much of this optimization requires accurate characterization of film thickness and absorption efficiency for the thin film used to manufacture the cells.

Spectroscopic ellipsometry is an optical measurement technique used to determine thin film thickness and optical constraints simply and accurately. This application note illustrates the ability of the technique to characterize photovoltaic devices. The materials commonly studied include: amorphous silicon, poly silicon, ZnO, ITO, SnO2, TiO2, Sinx, MgO, etc.

Spectroscopic ellipsometry is an ideal technique to characterize film thickness and optical constants for photovoltaic applications. Spectroscopic ellipsometers are also sensitive to the presence of rough overlayer and graded optical constants.

The technique provides the advantage to be fast, simple to operate and non-destructive for the characterization of the samples.
