Abstract

Long term stability is a major barrier for the commercialization of halide perovskite solar cells. Here Wu et al. demonstrate that a chemically inert and structural impermeability bismuth electrode interlayer greatly increases the stability of unencapsulated perovskite solar cells under harsh conditions.
