摘要： Disubstituted diaryloxybenzoheterodiazole compound of general formula (1): in which:—Z represents a sulfur atom, an oxygen atom, a selenium atom; or an NR5 group in which R5 is selected from linear or branched C1-C20, preferably C1-C8, alkyl groups, or from optionally substituted aryl groups;—R1, R2 and R3 are as defined in the claims. The said disubstituted diaryloxybenzoheterodiazole compound of general formula (I) can advantageously be used as a spectrum converter in luminescent solar concentrators (LSCs) which are in turn capable of improving the performance of photovoltaic devices (or solar devices) selected, for example, from photovoltaic cells (or solar cells), photovoltaic modules (or solar modules) on either a rigid substrate or a flexible substrate.

摘要： Process for the impregnation of a polymer substrate including at least one polymer, which comprises putting said polymer substrate in contact with at least one aqueous emulsion, preferably an aqueous microemulsion, including at least one organic additive. The impregnated polymer substrate obtained from said process can be advantageously used for obtaining polymer end-products having improved aesthetic characteristics (for example, impregnation with at least one dye) or stability characteristics (for example, impregnation with at least one stabilizer), which can be used in various fields such as, for example, the optical field (e.g., advanced optical components, laser applications), the medical field (e.g., the release of pharmaceutical substances), the agricultural field (e.g., release of pesticides), fragrances (e.g., release of fragrances). More specifically, said polymer substrate can be used in luminescent solar concentrators (LSCs) which, in their turn, can be advantageously used together, for example, with photovoltaic cells (or solar cells), or photoelectrolytic cells, in solar devices (i.e. devices for exploiting solar energy). Furthermore, said luminescent solar concentrators (LSCs) can be advantageously used together, for example, with photovoltaic cells (or solar cells), in photovoltaic windows.
