WebWith heterojunction solar cells, a conventional crystalline silicon wafer has amorphous silicon deposited on its front and back surfaces. This results in a couple of layers of thin-film solar that absorb extra photons that would otherwise not get captured by the middle crystalline silicon wafer. WebSep 29, 2024 · Polycrystalline solar cells are also referred to as “multi-crystalline,” or many-crystal silicon. Polycrystalline solar panels generally have lower efficiencies than monocrystalline cell options because there are many more crystals in each cell meaning less freedom for the electrons to move.
