Controlling the crystallization of perovskite films over large areas is key to the manufacturing of solar cells, but is difficult with existing fabrication methods. Now, researchers tailor the composition of the precursor ink to fabricate uniform and phase-pure perovskite layers, enabling a 15.3%-efficient photovoltaic module with an area of 205 cm2.
