▎ 摘　　要

NOVELTY - A tunneling junction of perovskite/perovskite two-end laminated solar battery comprises dense n-type or p-type semiconductor material and tunneling composite layer. The p-type or n-type semiconductor materials both have electron and hole transmission capability. The tunneling composite layer comprises perovskite/perovskite two-end laminated solar cell tunneling composite layer based on transparent conductive metal oxide nanocrystals. USE - Tunneling junction of perovskite/perovskite two-end laminated solar battery. ADVANTAGE - The battery has improved short circuit current density with excellent and solves the problem of unstable battery caused by diffusion of metal material.
