Sunlight Harvesting Transparent Windows

摘要

A photovoltaic system is formed as a window that is constructed of at least one polymer layer that is filled or decorated with metal nanoparticles and a window frame that includes one or more photovoltaic cells. The metal nanoparticles have a shape and size such that they display surface plasmon resonance frequencies in the near-infrared and/or the near-ultraviolet. The near-infrared and/or the near-ultraviolet radiations are scattered such that they are transmitted parallel to the face of the window to the photovoltaic cells, where an electrical current is generated.

1. A photovoltaic system, comprising a window and a frame comprising at least one photovoltaic cell, wherein the window comprises at least one combined nanoparticle polymer sheet comprising a transparent polymer and a multiplicity of metal nanoparticles, and wherein the photovoltaic cell resides in the frame perpendicular to a light receiving face of the window, and wherein the transparent polymer has at least partial transmittance in at least the visible and near IR regions of the electromagnetic spectrum.
