Exciton-Photon Critical Coupling in Size-Tailored Quantum Dots Enables >22% Efficient and Stable Inverted CsPbI3 Solar Cells
{{output}}
All-inorganic CsPbI3 inverted perovskite solar cells (PSCs) suffer from severe nonradiative recombination and interfacial defects, which limit their efficiency and stability. To address this, we developed an interface engineering strategy based on CsPbBr3 quan... ...
