Highly conductive transparent films are of significant interest in the field of thin-film photovoltaics. The solar cell type defines the necessary properties of the TCO used, as, besides the obvious qualities of transparency and conductivity, stability and morphology are important. The most significant properties of these aspects for front contacts in amorphous/microcrystalline silicon tandem, CIGS and CdTe solar cells are presented in this paper. Commonly used deposition techniques like CVD and sputter technology are described herein, focusing on particular techniques like SnO2:F and ZnO:B (CVD) and ZnO:Al (sputtering). New developments of deposition methods are also discussed.

The tenth edition of Photovoltaics International was published in November 2010. In this edition, Q-Cells SE demonstrates the benefits of laser marking, Fraunhofer IST presents TCO deposition techniques in Thin Films, and we take an in-depth look at the benefits of using selective emitters on an industrial scale with Neo Solar Power.
