Pinholes in absorber films are traditionally thought to degrade the performance of perovskite solar cells. The pursuit of efficient cells, especially the large-area ones, has thus mainly focused on realizing full-coverage absorber films. Herein, we demonstrate that such a paradigm can be broken in carbon-based, all-inorganic perovskite solar cells, by taking CsPbIBr2 absorber film as an ...
