By far, the most prevalent bulk material for solar cells is crystalline silicon (c-Si), also known as "solar grade silicon". Bulk silicon is separated into multiple categories according to crystallinity and crystal size in the resulting ingot, ribbon or wafer. These cells are entirely based around the concept of a p–n junction.
Solar cells can be made of a single layer of light-absorbing material (single-junction) or use multiple physical configurations (multi-junctions) to take advantage of various absorption and charge separation mechanisms. Solar cells can be classified into first, second and third generation cells.
Solar PV cell materials of different generations have been compared on the basis of their methods of manufacturing, characteristics, band gap and efficiency of photoelectric conversion.
This article provides an overview of what a solar cell (or also known as photovoltaic is (PV), inorganic solar cells (ISC), or photodiode), the different layers included within a module, how light is converted into electricity, the general production of inorganic solar cells, and what ideal materials (typically semiconductors) are used for it.
Silicon material is first melted and then poured into a mould to form p-crystalline silicon solar PV cells. The PCE of Si-based solar PV cells has been raised up to 24% since the discovery of these cells in Bell Laboratories .
