Abstract The organic-inorganic lead halide perovskite layer is a crucial factor for the high performance solar cell (PSC). We introduce CH 3 NH Br in precursor solution to prepare PbI 3−x x hybrid perovskite, and an uniform with improved crystallinity apparent grain contour obtained, resulting significant improvement of photovoltaic PSCs. effects on morphology, crystallinity, absorption property, charge carrier dynamics device characteristics are discussed, open circuit voltage depended...
Improvements in the light-harvesting capacity and carrier extraction are both significant to improve photovoltaic performance of perovskite solar cells (PSCs). It has been proved that local surface plasmon resonance (LSPR) based on metallic nanostructures is practical for capturing light enhance harvesting. Motivated by this, a special shaped Au nanoparticle, e.g., nanooctahedrons (Au NOs), with broadband LSPR peak suitable size controlled synthesized applied PSCs device. The power...
Recent advancements in large language models (LLMs) have demonstrated their impressive abilities various reasoning and decision-making tasks. However, the quality coherence of process can still benefit from enhanced introspection self-reflection.

The ${\mathit{L}}_{23}$ reflection spectra for single-crystal MgO, \ensuremath{\alpha}-${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$, and \ensuremath{\alpha}-${\mathrm{SiO}}_{2}$ are measured. These used to generate absorption that agree well with electron-total-yield electron-energy-loss measurements. Exciton features shown exist in the band gap by comparing valence-band maximum plus optical observed transition energies. energy splitting of...
