Silicon Solar Cell Parameters
An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick. However, thickness between 200 and 500µm are typically used, partly for practical issues such as making and handling thin wafers, and partly for surface passivation reasons. ... but higher levels of doping result in damage to the crystal ...

Gettering in silicon photovoltaics: A review
A key efficiency-limiting factor in silicon-based photovoltaic (PV) devices is the quality of the silicon material itself. With evolving cell architectures that better address other efficiency-loss channels in the device, the final device efficiency becomes increasingly sensitive to the contaminants in the silicon wafer bulk. However, due to cost constraints, …
