One of the leading approaches to enhancing the performance and stability of perovskite solar cells (PSCs) involves passivating the perovskite surface and grain boundaries with large ammonium salts. Here, we report the synthesis of furan-, thiophene-, and s ...

The creation of a universal quantum computer that can solve complex problems beyond the reach of classical computers - the so-called "quantum supremacy" - is an open challenge. For this to become a reality, a large number of qubits should be integrated in ...

The power conversion efficiency of perovskite solar cells continues to increase. However, defects in perovskite materials are detrimental to their carrier dynamics and structural stability, ultimately limiting the photovoltaic characteristics and stability ...

Scalable and sustainable photovoltaic technologies require low-cost and earth-abundant semiconducting materials. Zinc phosphide is purported to be an absorber material with optimal photovoltaic properties. Herein we report the electrical properties of Zn3P ...

Understanding the relationship between the crystal structure, chemical bonding, and lattice dynamics is crucial for the design of materials with low thermal conductivities, which are essential in fields as diverse as thermoelectrics, thermal barrier coatin ...

The dynamics of (few) electrons dissolved in an ionic fluid-as when a small amount of metal is added to a solution while upholding its electronic insulation-manifests interesting properties that can be ascribed to nontrivial topological features of particl ...

There exists a considerable density of interaggregate grain boundaries (GBs) and intra-aggregate GBs in polycrystalline perovskites. Mitigation of intra- aggregate GBs is equally notable to that of interaggregate GBs as intra-aggregate GBs can also cause d ...
