Research Highlights: Fostering the Dense Packing of Halide Perovskite Quantum Dots through Binary-Disperse Mixing

  By

Due to their versatile applications, perovskite quantum dot (PQD)-based optoelectrical devices have garnered significant research attention. However, the fundamental packing behavior of PQDs in thin films and its impact on the device performance remain relatively unexplored. Drawing inspiration from theoretical models concerning packing density with size mixtures, this study presents an effective strategy, namely, binary-disperse mixing, aimed at enhancing the packing density of PQD films.… Read More

Research Highlights: Bypassing the Non-Perovskite Yellow Phase: Revealing and Regulating the Crystallization Pathways for Efficient All-Inorganic Perovskite Solar Cells

  By


All-inorganic CsPbX3 perovskites have shown great potential in the photovoltaic community due to their excellent thermal stability and suitable bandgap for tandem applications. However, the formation of high-quality all-inorganic perovskite films remains a grand challenge, which requires delicate control over the high-temperature annealing process as the photo-inactive orthorhombic δ-phase is more stable than the photoactive perovskite phase at room temperature.… Read More
