Optimizing Wide Bandgap Perovskite Crystallization with Novel Additives to Enhance Component Performance
Core Innovation Summary Innovation: By introducing Piracetam as a crystal modifier, we optimize the nucleation and grain boundary structure of wide bandgap perovskite (WBG, 1.77 eV), achieving large grain sizes (1 μm), preferred orientation ((110) crystal plane), and one-dimensional needle-like structures (1D (Pi)PbI₃), significantly enhancing device efficiency and stability. Implementation Method: Molecular Regulation: Piracetam binds … Read more
