We discuss the major challenges in silicon ingot production for solar applications, particularly optimizing production yield, reducing costs, and improving efficiency to meet the continued high demand for solar cells. We review solar cell technology developments in recent years and the new trends.
Photovoltaic silicon ingots can be grown by different processes depending on the target solar cells: for monocrystalline silicon-based solar cells, the preferred choice is the Czochralski (Cz) process, while for multicrystalline silicon-based solar cells directional solidification (DS) is preferred.
A silicon ingot is the bulk form of crystalline silicon before it is thinly sliced into wafers. A high speed wire saw with diamond blades slices the ingot into round wafers about 300 to 1000 microns in thickness, and 25 mm to 300 mm in diameter. These wafers are used in solar cells in solar panels.
Significant advancements over the past 50 years have enabled the production of larger ingots today. Solar-grade silicon feedstock is melted in a quartz crucible and doped with the desired concentration of acceptors (for p-type ingots, doped with Gallium) or donors (for n-type ingots, doped with phosphorus).
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.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
