LIGHT CONCENTRATION DEVICE

摘要

Light concentration device comprising: —a primary luminescent solar concentrator (LSC) having a polygonal, circular or elliptic form, comprising at least one photoluminescent compound having a first absorption range and a first emission range; —at least a secondary luminescent solar concentrator (LSC) positioned outside said primary luminescent solar concentrator (LSC), said secondary luminescent solar concentrator (LSC) comprising at least one photoluminescent compound having a second absorption range superimposable to said first emission range and a second emission range. Said light concentration device can be advantageously used in photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photoelectrolytic cells. Said light concentration device can also be advantageously used in photovoltaic windows.

1. A light concentration device comprising:
a primary luminescent solar concentrator having at least one form selected from the group consisting of a polygon, a circle, and an ellipse, and comprising a photoluminescent compound having a first absorption range and a first emission range; and a secondary luminescent solar concentrator positioned outside the primary luminescent solar concentrator, wherein the secondary luminescent solar concentrator comprises a photoluminescent compound having a second absorption range, which is superimposable to the first emission range and a second emission range.
