Highly efficient and low hysteresis methylammonium-free perovskite solar cells based on multifunctional oteracil potassium interface modification

Bulk and interface defects are the culprits of power conversion efficiency (PCE) loss of the perovskite solar cells (PSCs). Meanwhile, notorious hysteresis is also an obstacle on the road of the PSCs commercialization process. Consequently, it is …
