    Barrier reinforcement for enhanced perovskite solar cell stability under reverse bias

    Stability of perovskite solar cells (PSCs) under light, heat, humidity and their combinations have been notably improved recently. However, PSCs have poor reverse-bias stability that limits their real-world ap...

    Design optimization of bifacial perovskite minimodules for improved efficiency and stability

    The efficiency and stability of bifacial perovskite solar modules are still relatively low. Here we report bifacial minimodules with front efficiency comparable to opaque monofacial counterparts, while gaining...

    Evolution of defects during the degradation of metal halide perovskite solar cells under reverse bias and illumination

    The efficiency and stability of perovskite solar cells are essentially determined by defects in the perovskite layer, yet their chemical nature and linking with the degradation mechanism of devices remain uncl...
