Abstract

Collection of photocarriers in Ga 1-xIn xN yAs 1-y solar cells is limited by the poor quality of the Ga 1-xIn xN yAs 1-y. Some reports have shown collection of photocarriers outside of the depleted layer in annealed Ga 1-xIn xN yAs 1-y, but the key to achieving the higher collection has been unclear. In this paper, we attempt to quantify the diffusion and collection lengths that contribute to the photocurrent in Ga 1-xIn xN yAs 1-y solar cells. The data imply that the effective μτ product for the lightly doped Ga 1-xIn xN yAs 1-y material may vary when a field is applied. We conclude that the fields present in most of our best Ga 1-xIn xN yAs 1-y cells are large enough to aid collection of photocarriers.
