Overview of available photovoltaic technologies *

Crystalline silicon technology: (Patterned Glass): Crystalline silicon cells are made from thin slices cut from a single crystal of silicon (monocrystalline) or from a block of silicon crystals (polycrystalline), their efficiency ranges between 12% and 17%. This is the most common technology representing about 90% of the market today.Three main types of crystalline cells can be distinguished:

  • Monocrystalline (Mono c-Si)
  • Polycrystalline (or Multicrystalline) (multi c-Si)
  • Ribbon sheets (ribbon-sheet c-Si)

Thin Film technology: (Float glass): Thin film modules are constructed by depositing extremely thin layers of photosensitive materials onto a low-cost backing such as glass, stainless steel or plastic. Thin film manufacturing processes result in lower production costs compared to the more material intensive crystalline technology, a price advantage which is currently counterbalanced by substantially lower efficiency rates (from 5% to 13%). Four types of thin film modules (depending on the active material used) are commercially available at the moment:

  • Amorphous silicon (a-Si)
  • Cadmium telluride (CdTe)
  • Copper Indium/gallium Diselenide/disulphide (CIS, CIGS)
  • Multi junction cells (a-Si/m-Si)

Other cell types: (Patterned glass): Today there are several other types of photovoltaic technologies developed , some starting to be commercialised or still at the research level, the main ones being:

  • Concentrated photovoltaic: Some solar cells are designed to operate with concentrated sunlight. These cells are built into concentrating collectors that use a lens to focus the sunlight onto the cells. The main idea is to use very little of the expensive semiconducting PV material while collecting as much sunlight as possible. Efficiencies are in the range of 20 to 30%.
  • Flexible cells: Based on a similar production process to thin film cells, when the active material is deposited in a thin plastic, the cell can be flexible. This opens the range of applications, especially for building integration (roofs-tiles) and end-consumer applications.
