Research Highlights: Regulating the Crystallization Kinetics and Lattice Strain of Lead-Free Perovskites with Perovskite Quantum Dots

  By

The growth of high-quality tin-based perovskite films remains a grand challenge due to the uncontrollable crystallization kinetics. Here, we report a facile strategy to realize an epitaxial-like growth of highly oriented tin-based perovskite films with the assistance of perovskite quantum dots (PQDs). Synchrotron-based in situ X-ray scattering results reveal that PQDs can act as nucleation centers to promote the growth of highly oriented perovskite crystals for both FASnI3 and MASnI3 systems.… Read More

Research Highlights: Computational Chemistry-Assisted Design of Non-Fullerene Acceptor Enables 17.4% Efficiency in High-Boiling-Point Solvent Processed Binary Organic Solar Cells

  By


Designing new high-performance non-fullerene acceptors is the key driving force for the development of organic solar cells (OSCs). In this work, a new acceptor, BOEH‑4Cl, was designed based on the end-group chlorination of L8-BO. Theoretical calculations successfully predicted the expected experimental results based on the optoelectronic properties of BOEH-4Cl and L8-BO and intermolecular interaction of PM6/BOEH-4Cl or L8-BO.… Read More
