Expressions for transient photocurrents and photovoltages are derived by solving the time-dependent diffusion equation for both horizontal- and vertical-junction cells. Four cases are dealt with (1) when the light is switched off at T = 0; (II) when the light is switched on at T = 0; (III) when the cell is illuminated by a square pulse of finite duration; (IV) when it is illuminated by a delta pulse. Assuming certain values for the parameters of the material of the cell, numerical results are reported for conventional cells of diffused layer thickness 0.5 and 5 ..mu..m and one vertical-junction cell. The use of such studies for measurement of life times and diffusion lengths of carriers is suggested.
