The silicon used to make mono-crystalline solar cells (also called single crystal cells) is cut from one large crystal. This means that the internal structure is highly ordered and it is easy for electrons to move through it. The silicon crystals are produced by slowly drawing a rod upwards out of a pool of molten silicon.

Single crystal solar cells are often 15.6 × 15.6 cm 2, giving a total current of almost 9 – 10A from a module. The table below shows the output of typical modules at STC. I MP and I SC do not change that much but V MP and V OC scale with the number of cells in the module.
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.
Transfer matrix method and PC1D simulation software were used additionally to simulate crystalline silicon solar cells with considered double and multi-layer ARC films on their front surface with calculated thicknesses. Average reflectance (400-1100 nm) of silicon surface by Fresnel equations with triple layer ARC was around 2.72%.
