Central to this solar revolution are Photovoltaic (PV) solar cells, experiencing a meteoric rise in both demand and importance. For professionals in the field, a deep understanding of the manufacturing process of these cells is more than just theoretical knowledge.
The solar cell manufacturing process is complex but crucial for creating efficient solar panels. Most solar panels today use crystalline silicon. Fenice Energy focuses on high-quality, efficient production of these cells. Monocrystalline silicon cells need purity and uniformity.
The solar cell production industry is a complex web of different players, each with their unique roles. Solar PV module production lies at the heart of this intricate market. It begins with suppliers of silicon wafers, the first step in the photovoltaic supply chain. These wafers go through advanced processes to become clean energy solutions.
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.
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.
