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.
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.
Silicon (Si) wafer-based solar cells currently account for about 95% of the photovoltaic (PV) production and remain as one of the most crucial technologies in renewable energy. Over the last four decades, solar PV systems have seen a staggering cost reduction due to much reduced manufacturing costs and higher device efficiencies.
It all starts with quartz, rich in silicon. The process heats up to extract pure silicon. This uses the floating zone technique for purity. Pure silicon is key for multi-crystalline silicon cells and mono-crystalline silicon cells, vital in solar energy today. The next step is turning pure silicon into silicon wafers.
All functional layers are deposited on the substrate and scribed to separate subcells electrically connected. In silicon wafer-based solar cells, the front side is engineered with two optical functions: texturisation through a dry or wet etch process and antireflective coating.
Silicon solar wafers can be made from either quartz rock or silica sand, although quartz rock is a considerably more expensive material. Once extracted, silica sand or quartz must undergo a smelting process to produce metallurgical silicon.
