The production process from raw quartz to solar cells involves a range of steps, starting with the recovery and purification of silicon, followed by its slicing into utilizable disks – the silicon wafers – that are further processed into ready-to-assemble solar cells.
While most solar PV module companies are nothing more than assemblers of ready solar cells bought from various suppliers, some factories have at least however their own solar cell production line in which the raw material in form of silicon wafers is further processed and refined.
A PV module (or panel) is an assembly of solar cells in a sealed, weather-proof packaging and is the fundamental building block of photovoltaic (PV) systems. All finished solar cells are tested on electrical and optical parameters for quality control and are sorted on the basis of current or power output.
Cell Fabrication – Silicon wafers are then fabricated into photovoltaic cells. The first step is chemical texturing of the wafer surface, which removes saw damage and increases how much light gets into the wafer when it is exposed to sunlight.
For real-world applications, photovoltaic modules are fabricated by electrically connecting typically 36 to 72 solar cells together in a so-called PV module. A PV module (or panel) is an assembly of solar cells in a sealed, weather-proof packaging and is the fundamental building block of photovoltaic (PV) systems.
The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.
Following the initial pre-check, the front surface of the silicon wafers is textured to reduce reflection losses of the incident light. For monocrystalline silicon wafers, the most common technique is random pyramid texturing which involves the coverage of the surface with aligned upward-pointing pyramid structures.

Silicon PV. Most commercially available PV modules rely on crystalline silicon as the absorber material. These modules have several manufacturing steps that typically occur separately from each other.
However, first-generation silicon-based solar cells (mono- and polycrystalline silicon wafer) have dominated over 90% of the PV market due to relative abundant raw materials such as silicon (Si), even though the maximum theoretical energy conversion efficiency of PV devices is limited to 33% [54]. Moreover, silicon-based solar cells have a disadvantage that …
The silicon wafer usually already starts off by already being doped with boron. To form the n-type layer, phosphorus has to be introduced to the wafer at high temperatures of around 870 °C for 15–30 min in order for it to penetrate into the wafer. The excess n-type material is then chemically removed.
expansion between silicon wafer and interconnection ribbon material is the reason of this stress19). Additionally, the bending of the interconnection ribbons at the edge of the wafer causes further stress. This affects the reliability of the whole module assembly20-24). In the later section we will discuss about the
