Minority Carriers

The photonic's method is used in the study of monocristalline silicon solar cell (N+P). The induced photocurrent in the cell is analyzed with respect to the technological parameters such as the optical absorption coefficient of silicon and the emitter and base thickness. The spatial and frequential variations of the photocurrent of the cell, when the latter is illuminated by a sinusoidal modulated light, allow access to the diffusion length and lifetime of the minority carriers generated in a given region of the cell. In this paper, the physical parameters related to the base region are determined. In addition, this access is shown to be possible only when the total photocurrent of the cell is reduced to the base diffusion photocurrent.
