A Thiourea Competitive Crystallization Strategy for FA‐Based Perovskite Solar Cells

The solution process of perovskite solar cells may lead to widespread defects in the device, causing severe nonradiative recombination and the loss of conversion efficiency. Herein, a strategy of embedding thiourea into perovskite to manipulate the crystallization process and passivate the defects s...
