Abstract

In this paper, planar photodiodes based on perovskite were fabricated and characterized. We explored the relationship between channel length and photo-generated current. The study demonstrates that the photo-generated current generated by planar photodiode at weak light is hardly affected by the channel length. However, due to the influence of the diffusion mechanism, the photo-generated current gradually increases with the channel length under strong light. Our study provides a reasonable explanation for the diffusion mechanism of photo-generated carriers in horizontal structure.
