We investigated the dark current components of thin planar InGaAs photodiodes grown by metalorganic vapor-phase epitaxy for optical nano-resonators. Owing to their high electric field enhancement, nano-resonators make it possible to substantially reduce the thickness of the active region to about 100 nm all the while maintaining high quantum effici...
Recombination of charge carriers limits the open circuit voltage and hence efficiency of chalkopyrite thin film solar cells. It has been the goal of this work to determine the recombination mechanism in thin film solar cells based on CuInS-2. Development of a preparation process that yields state of the art solar cells has been a necessary first st...
