Silicon wafer-based photovoltaic cells are the essential building blocks of modern solar technology. EcoFlow’s rigid, flexible, and portable solar panels use the highest quality monocrystalline silicon solar cells, offering industry-leading efficiency for residential on-grid and off-grid applications.
Various types of wafers can be used to make solar cells, but silicon wafers are the most popular. That’s because a silicon wafer is thermally stable, durable, and easy to process. The process of making silicon wafer into solar cells involves nine steps. In this article, we will discuss the first three steps.
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.
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.
Silicon wafers have fueled the solar revolution since 1954, though the technology has come a long way since then! Thanks to constant innovation, falling prices, and improvements in efficiency, silicon wafer-based solar cells are powering the urgent transition away from producing electricity by burning fossil fuels.
Both polycrystalline and monocrystalline solar panels use wafer-based silicon solar cells. The only alternatives to wafer-based solar cells that are commercially available are low-efficiency thin-film cells. Silicon wafer-based solar cells produce far more electricity from available sunlight than thin-film solar cells.
