The ac photocurrent (PC) and photothermal reflectance (PTR) spectroscopic response theory of a semiconducting p-n junction developed in part I [J. Appl. Phys. 66, ⧠⧠⧠⧠ (1989)] is applied to theoretical simulations to identify the influence of the various electronic and geometrical device parameters involved. The theory is further tested in an experimental configuration with a commercial solar cell. The experimental ac photocurrent and photothermal reflectance data exhibited satisfactory agreement with the theoretical model, and yielded, respectively, experimental values for the minority lifetimes τp and τn. A combination of PC and PTR data yielded reasonable Ln estimates.
