Problems solved by technology

[0016] Although 4,7-bis(thiophen-2'-yl)-2,1,3-benzothiadiazole (DTB) absorbs a significant portion of the solar spectrum, 4,7-bis(thiophen-2'-yl) - 2,1,3-Benzothiadiazole (DTB) has less absorption in the higher wavelength region of the solar spectrum, which is associated with yellow radiation (yellow radiation) and red radiation ( red radiation) accordingly, so the yellow and red radiation cannot be converted into other radiation that is more efficiently utilized by the photovoltaic cell

[0064] 6g of polymethylmethacrylate Altuglas VSUVT 100 (PMMA) and 76.5mg of 4,7-bis(2',2"-dithiophen-5'-yl)-2,1,3-benzothiadiazole (QTB ) was dissolved in 30ml of 1,2-dichlorobenzene. Subsequently, the resulting solution was uniformly deposited on a polymethyl methacrylate plate Almglas VSUVT 100 (PMMA) (size 90x90x6mm) using a doctor blade type film coater, and The solvent was allowed to evaporate for 24 hours at room temperature (25° C.) in a small air stream. A red transparent plate (plate 1 ) was obtained, the color being imparted by a thin film whose thickness proved to range from 50 μm to 350 μm.

Abstract

Luminescent solar concentrator (LSC) comprising at least one disubstituted benzothiadiazole compound having general formula (I).The present invention also relates to the use of at least one disubstituted benzothiadiazole compound in the construction of luminescent solar concentrators (LSC).

Description

technical field [0001] The present invention relates to a luminescent solar concentrator (LSC) comprising at least one disubstituted benzothiadiazole compound. [0002] The invention also relates to the use of at least one disubstituted benzothiadiazole compound for the construction of luminescent solar concentrators (LSC). [0003] The invention also relates to a photovoltaic device selected from, for example, a photovoltaic cell, a photovoltaic module, a solar cell, a solar module on a rigid support (support) and a flexible support, said photovoltaic device comprising a luminescent solar concentrator A luminescent solar concentrator (LSC) comprising at least one disubstituted benzothiadiazole compound. Background technique [0004] It is known that single-junction photovoltaic cells cannot efficiently utilize all solar radiation. In fact, their efficiency is greatest only in a certain spectral range, which includes a part of visible radiation and a part of infrared radia...
