Crystalline modules (mono + poly)

Polycrystalline or multi-crystalline modules have dark blue solar cells cut from cast silicon blocks up of numerous small silicon crystals. Polycrystalline modules are slightly less efficient than monocrystalline ones but are less costly to manufacture because the production process is not so complicated. These most widely used modules are suitable for photovoltaic systems on family homes as well as for larger systems on industrial roofs.

Monocrystalline modules work with black solar cells and are made of a single silicon crystal with a regular structure. The base material for production is drawn silicon blocks. High-performance saws cut crystal into thin sheets, roughly 0,2 mm thick, and more commonly known as wafers. These are then chemically processed and contacts attached. Monocrystalline cells achieve a high level of efficiency in excess of 17% and are particularly suitable for small to medium-sized systems where space is limited.

Thin-film modules

Thin-film modules have a different structure from monocrystalline and/or polycrystalline modules. The photovoltaic effect that ensures electricity flows is the same, but the actual layers that make up thin-film modules are only about 2 microns thick. These layers of silicon or other semiconductors are steamed onto a panel of glass in a similar way as for a flat screen.
