Most solar panels today use crystalline silicon. Fenice Energy focuses on high-quality, efficient production of these cells. Monocrystalline silicon cells need purity and uniformity. The Czochralski process achieves this by pulling a seed crystal out of molten silicon. This creates a pure silicon ingot. It is then cut into wafers, making highly efficient cells. The multicrystalline

The remaining 4% consists of other materials, mostly cadmium telluride. Monocrystalline silicon PV cells can have energy conversion efficiencies higher than 27% in ideal laboratory conditions.
The development of the PV industry is a vigorous competition between mono- and multi-crystalline silicon, as well as their crystal growth technologies, which will be focused on shortly. Crystal growth was not the single factor in getting the Holly Grail of the ultimate technology; the slicing and advanced solar cell concepts played crucial roles.

The manufacturing process for crystalline silicon solar module can be split into 4 main steps (read more about the silicon supply chain): Mined quartz is purified from silicon dioxide into solar-grade silicon. There are many smaller steps to this process, including heating up the quartz in an electric arc furnace.
The importance of crystallization methods in solar cell silicon ingot quality. The effects of the Czochralski (Cz) and directional solidification (DS) methods on microstructure and defects are reported. Challenges in monocrystalline and multicrystalline silicon ingot production are discussed.
Thus, the final ingot has a multicrystalline structure. Crystallographic defects, such as dislocations and grain boundaries, limit significantly the final solar cell efficiency , as they tend to trap transition metal impurities and increase the recombination activity of the material.
