Solar cells are generally the thickest component of a solar panel, and their thickness can vary from about 200 micrometers (0.2mm) to 400 micrometers (0.4mm). The other main component of a solar panel is the glass cover, which has a typical thickness of 3mm. So, all in all, a small solar panel typically has a thickness of about 6.2mm.
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.
Monocrystalline solar panels are produced from one large silicon block in silicon wafer formats. The manufacturing process involves cutting individual wafers of silicon that can be affixed to a solar panel. Monocrystalline silicon cells are more efficient than polycrystalline or amorphous solar cells.
Polycrystalline solar cells are also silicon cells, but rather than being formed in a large block and cut into wafers, they are produced by melting multiple silicon crystals together. Many silicon molecules are melted and then re-fused together into the panel itself.
A typical silicon PV cell is a thin wafer, usually square or rectangular wafers with dimensions 10cm × 10cm × 0.3mm, consisting of a very thin layer of phosphorous-doped (N-type) silicon on top of a thicker layer of boron-doped (p-type) silicon. You might find these chapters and articles relevant to this topic.
At this point, it is argued, further progress in photovoltaics will rely on emerging thin-film solar cell technologies based on amorphous materials, compound semiconductors, or perhaps even organic polymer, nanomaterials, or other types of solar cells with no current analogues.
