Several phenomena affecting the V-I characteristics of PIN thermophotovoltaic converter diodes are discussed, including diffused layer recombination, minority carrier injection, and non-planar effects. Analysis of the distributed resistance is developed to estimate the optimum converter dimensions. Experimental results on several diodes are presented, and their behavior explained in terms of the distributed resistance and an assumed lifetime law. A study of the mobility in the high injection intrinsic region was made, and an empirical formula for the variation with injection level established. It is shown that this formula lies between two proposed theories for mobility variation. Author
