Monocrystalline solar panels are created by growing a single crystal structure. The process begins by placing a seed crystal in molten silicon. This seed is then carefully drawn up with the molten silicon forming a shell around it, which cools and solidifies into a single crystal silicon structure, hence the name monocrystalline.
The best single-junction solar cell efficiency for unconcentrated light is currently obtained with thin GaAs devices with a record value of 29.1%.

A single silicon crystal seed and molten silicon are put into a square mold and allowed to set. The silicon cools at different rates as the outside cools more quickly and thus sets first. The uneven setting results in the creation of many different crystals (hence the name polycrystalline) giving the panel its sparkly, multicolored appearance.
Perovskite crystal facets greatly impact the performance and stability of their corresponding photovoltaic devices. Compared to the (001) facet, the (011) facet yields better photoelectric properties, including higher conductivity and enhanced charge carrier mobility.
