On 6-7 July, CBRTP participated in the 8th Congress of the Polish Vacuum Society, where the publication on ''Optical method for testing the homogeneity of thin-film electrodes for photovoltaic cells" was presented in a poster session.

The paper presents a new non-destructive optical method for testing the homogeneity of photovoltaic cells. A spectroscopic ellipsometry method was used to study the uniformity of thickness and optical constants (refractive index and extinction coefficient) of deposited electrodes with a large surface area (15.6 cm x 15.6 cm). In-house laboratory resources (PVD reactor and ALD reactor) were used for sputter deposition of metallic electrodes (Al.,Mo) and for deposition of transparent electrodes (ZnO:AL).

The measurement results presented in the publication allowed an accurate assessment of the homogeneity of the evaluated parameters. In contrast to microscopic methods, e.g. AFM, the optical method described in the paper, allows the analysis of large samples, e.g. an electrode for a photovoltaic cell with standard dimensions of 15.6 cm x 15.6 cm.

The method can be particularly useful for photovoltaic cell manufacturers.

The authors of the paper are: S. Iwanek, J.Sanetra, K.W. Marszałek
