Said intermediate layer has a transparency of at least 90% for infrared light between 780 nm and 1200 nm and said interference filter is corrugated and composed of a multilayer comprising a plurality of dielectric layers designed to transmit at least 75% of the total incident solar infrared light between 780 nm and 1200 nm, and to reflect and diffuse incident visible solar light such that the perceived color of said reflected and diffused visible light by any observer positioned anywhere to the incident light side of said solar photovoltaic module and looking towards the front element of said solar photovoltaic module is defined by a Y10 tristimulus value not lower than 50 defined by an x value of 0.20 to 0.45 and a y value of 0.20 to 0.45 in a chromaticity diagram of a CIE 1964 Yxy color system using a white light source measured with a D65 light source with a 10-degree angular field. | 03-03-2016 |

20160190370 | WAVELENGTH CONVERTING STRUCTURE FOR NEAR-INFRARED RAYS AND SOLAR CELL COMPRISING THE SAME - Provided is a wavelength converting structure for near-infrared rays and a solar cell using the same. More particularly, provided is a novel wavelength converting structure for near-infrared rays using gap plasmon characteristics and up-conversion nanoparticles. When applying the wavelength converting structure for near-infrared rays to a solar cell, it is possible to convert the light within a wavelength range of near-infrared rays into electric energy so that the photoconversion efficiency may be improved. | 06-30-2016 |
