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.
通式(1)的二取代二芳基苯并二唑化合物: 其中:-Z 代表
硫原子、氧原子、
硒原子;或 NR5 基团,其中 R5 选自直链或支链 C1-C20,优选 C1-C8,烷基或任选取代的芳基;-R1、R2 和 R3 如权利要求书中所定义。通式(I)的上述二取代二芳基苯并二氮杂环唑化合物可有利地用作发光太阳能聚光器(LSCs)中的光谱转换器,而LSCs反过来又能提高光电设备(或太阳能设备)的性能,例如,可选自刚性基板或柔性基板上的光电池(或太阳能电池)、光电模块(或太阳能模块)。
