Structure and Properties of Quasi-Monocrystalline Silicon Thin-Films TITUS J. RINKE, RALF B. BERGMANN, AND JORGEN H. WERNER Institut fdr Physikalische Elektronik, Universittit Stuttgart, Pfaffenwaldring 47, D-70569 Stuttgart, Germany, titus.rinke@ipe.uni-stuttgart.de ABSTRACT Photovoltaic cells are made from a variety of semiconductor materials that vary in performance and cost. Because monocrystalline solar cells are made out of a single crystal of silicon, electrons are able to flow easier through the cell, which makes the PV cell efficiency higher than other types of solar panels. The fabrication is totally made internally from the pulling process to get the ingot up to the final step which is the cleaning process. • The crystal structure of silicon forms a diamond cubic 0000066614 00000 n The diamond cubic crystal structure Silicon belongs to the cubic crystal system and has a diamond structure.
