Multi-crystalline silicon solar wafer are the working horses of the rapidly developing photovoltaic market. The availability and cost efficiency but, even more important, the improved wafer quality and the understanding how to process multi-crystalline silicon wafers into highly efficient solar cells are important factors in this development. In this paper multi-crystalline silicon wafer manufacturing technologies both in industrial production as well as under development are outlined. Important wafer characteristics such as oxygen-, carbon and metallic impurities are described and experimental links to solar cell efficiency are exemplary demonstrated.
