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.
Another relevant field of research is the reduction of the wafer thickness in order to produce more wafers per kilogram silicon. Finally, the wafering process step, in combination with the material quality, defines the mechanical properties of the final solar cell, as the wafering process can damage the wafer’s surface.
Silicon wafer-based solar cells dominate commercial solar cell manufacture, accounting for about 86% of the terrestrial solar cell industry. For monocrystalline and polycrystalline silicon solar cells, the commercial module efficiency is 21.5% and 16.2% [10–12].
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.
Wire sawing will remain the dominant method of producing crystalline wafers for solar cells, at least for the near future. Recent research efforts have kept their focus on reducing the wafer thickness and kerf, with both approaches aiming to produce the same amount of solar cells with less silicon material usage.
Stephen J. Fonash, in Solar Cell Device Physics (Second Edition), 2010 Light trapping has long been achieved in wafer-based solar cells using 2- to 10-μm pyramidal structures etched into the cell’s surface. Using this micron-length scale technology is obviously out of the question in thin-film structures.
