Lecture
This lecture covers the process of preparing silicon material and wafers for photovoltaic applications. It includes topics such as the crystalline silicon standard chain, Czochralski process, ingot fabrication, wafering techniques, and the mechanical properties of silicon. The instructor discusses the purification of metallurgical grade silicon, the Siemens process, and alternative approaches like the String Ribbon and SiGen PolyMax processes. The lecture also addresses the importance of wafer quality, costs, and energy efficiency in the production of solar cells.
