Light concentrator based on quantum dot, and photovoltaic module including the same

Abstract

A light concentrator based on a quantum dot may include a resin film layer in which quantum dots are dispersed, an upper layer in contact with an upper surface of the resin film layer, and a lower layer in contact with a lower surface of the resin film layer. Each of the upper layer and the lower layer may be selected from a glass layer or a polymer layer. A photovoltaic module may include the quantum dot-based light concentrator. By optimally adjusting the longest wavelength of the quantum dots, the average transmittance of the glass layer, the material of the polymer layer, and the cross-sectional aspect ratio (length/thickness) of the light concentrator, it is possible to maximize the efficiency of the quantum dot-based light concentrator and increase the efficiency of the photovoltaic module including the light concentrator.
