Contents I. Introduction
The charge collection probability, as we know, is the probability that a photon-generated minority carrier can contribute to the short circuit current of a solar cell. A photon-generated electron-hole pair may be transported through the cell and go to the external circuit. On the other hand, it may recombine with other carriers or be captured by any defects within the cell. As a result, charge collection probability is one of the most important parameters of a solar cell, because it is related to the quality of the material and the physical design of the cell. Different from the parameters like external quantum efficiency, short-circuit current, and photon conversion efficiency, which can be measured from experiment directly, collection probability are usually calculated from other parameters.
