Abstract: We present an approach for examining and understanding the impact of material and process variations on solar cell efficiencies using the example of an industrial feasible multicrystalline silicon (mc-Si) passivated emitter and rear cell (PERC) process.
In solar cell fabrication, crystalline silicon is either referred to as the multicrystalline silicon (multi-Si) or monocrystalline silicon (mono-Si) [70–72]. The multi-Si is further categorized as the polycrystalline silicon (poly-Si) or the semi-crystalline silicon, consisting of small and multiple crystallites. This multiplicity causes a visible grain in the structure of the solar cell. On

We briefly describe the different silicon grades, and we compare the two main crystallization mechanisms for silicon ingot production (i.e., the monocrystalline Czochralski process and multicrystalline directional solidification). We highlight the key industrial challenges of both crystallization methods.
