The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single silicon crystal. In contrast, polycrystalline solar panels have solar cells made from many silicon fragments melted together.
[pdf] The silicon cells in monocrystalline solar panels produce electricity through the photovoltaic (PV) effect. This effect occurs when sunlight hits the silicon crystal and excites the electrons inside. The movement of these electrons is what generates electricity.
[pdf] But now, new technology solar panels – bifacial and mono PERC – are widely used. Many new higher-performing materials have been discovered – perovskite, heterojunction and tandem solar cells.
