Collection of Photocarriers in GaxIn1-xNyAs1-y Solar Cells

    Research output: Contribution to conferencePaper


    Collection of photocarriers in GaxIn1-xNyAs1-y solar cells is limited by the poor quality of the GaxIn1-xNyAs1-y. Some reports have shown collection of photocarriers outside of the depleted layer in annealed GaxIn1-xNyAs1-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 thephotocurrent in GaxIn1-xNyAs1-y solar cells. The data imply that the effective product for the lightly doped GaxIn1-xNyAs1-y material may vary when a field is applied. We conclude that the fields present in most of our best GaxIn1-xNyAs1-y cells are large enough to aid collection of photocarriers.
