The majority of silicon solar cells are fabricated from silicon wafers, which may be either single-crystalline or multi-crystalline. Single-crystalline wafers typically have better material parameters but are also more expensive. Crystalline silicon has an ordered crystal structure, with each atom ideally lying in a pre-determined position.
Sequential manufacturing processes of a silicon solar cell Solar-grade Cz-Si ingots are sliced into round wafers that are trimmed to a pseudo-square shape.
Single crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module.
The silicon substrate is converted into solar cells using technologies based on semiconductor device processing and surface-mount technology (SMT). The cell process technology (Sect. 51.4) mainly consists of wafer surface etching, junction formation, antireflection coating deposition, and metal contact formation.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
The production of solar-grade silicon, that is mainly used in solar and electrical applications, from metallurgical-grade silicon requires the reduction in impurities by five orders of magnitude via the so-called metallurgical route [5, 6, 7, 8]. Directional solidification (DS) is an essential step in this approach.
