P–n photovoltaic junctions are essential building blocks for optoelectronic devices for energy conversion. However, this photovoltaic efficiency has almost reached its theoretical limit. Here, a brand‐new excitonic photovoltaic effect in 2D CsPbBr3/CdS heterostructures is revealed. These heterostructures, synthesized by epitaxial growth, display a clean interface and a strong interlayer coupling....
As a promising candidate for optoelectronics, one‐dimensional CdS nanostructures have drawn great scientific and technical interest due to their interesting fundamental properties and possibilities of utilization in novel promising optoelectronical devices with augmented performance and functionalities. This progress report highlights a selection of important topics pertinent to optoelectronical applications...
High-quality, uniform CdS one-dimensional (1D) micro/nanostructures with different morphologies, e.g. microrods, sub-microwires and nanotips, are fabricated through a facile and effective thermal evaporation process. Their structural, cathodoluminescence and field-emission (FE) properties are systematically investigated. Microrods and nanotips exhibit sharp near band edge (NBE) emission and broad...
