Research Background Perovskite materials have become an ideal choice for next-generation photovoltaic materials due to their excellent optoelectronic properties and low-cost manufacturing processes. They are widely used in solar cells, photodetectors, and light-emitting devices. Compared to traditional silicon-based materials, perovskite materials offer significant advantages such as higher light absorption efficiency, broader spectral response, and lower … Read more

Optimizing Wide Bandgap Perovskite Crystallization with Novel Additives to Enhance Component Performance

2025-10-13 by boardor

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

Wuhan University’s Ke Weijun in Nature Nanotechnology: Piracetam Shapes Wide-Bandgap Perovskite Crystals for Scalable Perovskite Tandems

2025-10-13 by boardor

Fully perovskite tandem solar cells (TSC) exhibit excellent performance and wide applicability. However, significant challenges remain in bridging the power conversion efficiency (PCE) gap between small-area and large-area (> 1cm2) devices, which poses a substantial barrier to the commercialization of fully perovskite TSC. In light of this, the team led by Ke Weijun at Wuhan … Read more
