Summary
Researchers have developed a predictive framework to optimize 2D perovskite solar cell design by better understanding how excitons (electron-hole pairs) behave in these materials. The study focuses on dielectric screening — how the material's internal environment weakens the attraction between electrons and holes — which directly impacts how efficiently sunlight is converted into electricity. By isolating and understanding this mechanism, the framework aims to guide the design of more efficient and stable perovskite solar cells, addressing a key challenge in the field.
