Abstract

The multicrystalline silicon produced by different growth processes exhibit quite different chemical, physical and electrical properties. The electrical properties depend in a very complicated manner on the growth history of materials. This study addresses the analysis of the influence of the electromagnetic casting (EMC) growth process on the physical and electrical properties of the materials in order to determine the main limiting factors of this growth method for high-efficiency solar cells. We compare results for the conventional Polix material based on molded ingots supplied by Photowatt. Furthermore, we intend to understand the influence of thermal treatments on the electrical properties of these specific materials.
