PLATE-TYPE SILICON, METHOD OF PRODUCING THE PLATE-TYPE SILICON, SOLAR BATTERY, AND BASE PLATE FOR PRODUCING THE PLATE-TYPE SILICON

摘要

A plate-type silicon, a method of producing the plate-type silicon, a solar battery using the plate-type silicon, and a base plate for producing the plate-type silicon. A plate-type silicon that is low cost, does not require a slicing step and has an improved yield ratio. The plate-type silicon is a type of silicon that is formed by immersing a base plate in molten silicon and allowing silicon to form on the surface of the base plate. The plate-type silicon has a first face that is a main face and other faces continuously formed from the first face. The other faces include at least one face whose normal vector is antiparallel or forms an obtuse angle with respect to a normal vector of the first face, and the faces are shaped so as to be coupled to the base plate so that the plate-type silicon is prevented from falling from the base plate. A low-cost solar battery is provided by the use of the plate-type silicon.
