Change to the cast

Few in the industry predicted the speed at which monocrystalline technology would develop, or the impressive cost reductions it would achieve by 2019. This has left producers of multicrystalline products facing rapidly shrinking market share and struggling to compete on a cost per watt basis. Many are now turning to cast mono processes, essentially creating a monocrystalline, or ‘mono-like’ silicon ingot in a multicrystalline furnace, to reach higher efficiencies and extend equipment lifetimes.
