Experiments to evaluate high-temperature rolling as a low-cost process for silicon solar cellsMechanical rolling (a process used in industry for producing large quantities of metallic sheet and strip) has been suggested for the rapid low-cost manufacture of silicon sheet to be used for photovoltaic power generation equipment, such as solar arrays. The advantages of rolling include: high rates of production, wide sheets as products, good control of dimension, and (in the case of solar grade silicon) minimal development of impurities. Experiments have been performed using high-temperature, high-speed compression of polycrystalline silicon cylinders. Metallography and X-ray diffraction techniques have been used to examine the samples both before and after compression, and a model process has been designed to evaluate the technical practicality and economic feasibility of the method.
