摘要： A photovoltaic device has nanoparticles sandwiched between a conductive substrate and a charge selective transport layer. Each of the nanoparticles has a ligand shell attached to the nanoparticle core. A first type of ligand is electron rich and attached to one hemisphere of the nanoparticle core, while a second type of ligand is electron poor and attached to an opposite hemisphere of the core. Consequently, the ligand shell induces an electric field within the nanoparticle, enhancing the photovoltaic effect. The arrangement of ligands types on different sides of the nanoparticle is obtained by a process involving ligand substitution after adhering the nanoparticles to the conductive substrate.

摘要： A system for imaging a substrate can comprise an image data source, an electromagnetic radiation source operatively connected to the image data source and configured to emit electromagnetic radiation in accordance with information provided by the image data source, and a DBR film applied to a substrate. The DBR film can comprise two types of film layers, wherein the two types of film layers are each stable at ambient temperature, each of the two types of film layers having a glass transition temperature (TG) that is lower than the temperature needed to produce deformation of bulk material of the two types of film layers upon interaction with the electromagnetic radiation.
