Issue Date: | 2012 | Publisher: | IEEE | Source: | 2012 38TH IEEE PHOTOVOLTAIC SPECIALISTS CONFERENCE (PVSC), IEEE, p. 2628 -2631 | Abstract: | Mechanical alloying and bead milling techniques were used for the low cost preparation of precursor inks for printing CIS-Se absorber layers. The plate shaped microflake particle precursor is composed of nanostructured elemental Copper-Indium-Sulfur and Selenium. The high aspect ratio microflakes have a typical thickness around 200 nm and a diameter of 1-5 mu m. The plate shape of the microflakes facilitates the deposition of a high quality film during the coating process. Moreover, the nanostructured nature of the microflakes improves the sintering behavior during selenization. The milling technique is relatively low cost, easily up-scalable, fast and very flexible in targeted composition. | Notes: | Zaghi, AE (corresponding author), Katholieke Univ Leuven, Dept Met & Mat Engn, B-3001 Louvain, Belgium. | Keywords: | CIGS;Printing solar cells;microflake;milling | Document URI: | http://hdl.handle.net/1942/31560 | ISBN: | 978-1-4673-0066-7 | ISI #: | WOS:000309917802209 | Category: | C1 | Type: | Proceedings Paper |
