S. Bastide et al., PHOTOELECTROCHEMICAL DIFFUSION LENGTH MEASUREMENTS ON P-TYPE MULTICRYSTALLINE SILICON FOR PHOTOVOLTAIC APPLICATIONS, Journal of the Electrochemical Society, 142(3), 1995, pp. 1024-1030
We report photoelectrochemical measurements of diffusion lengths in p-
type multicrystalline silicon used for photovoltaic solar cells. We sh
ow that, under some conditions, this method provides a very practical
means for rendering an account of the quality nature of this material
through diffusion length variations. The results obtained during two y
ears of use of this method in the industrial processing of photovoltai
c cells are presented and discussed.
