by incorporating electron‐donating substituents at various positions of the quinoxalinoid moiety. Some of the dyes and mixtures thereof were found to exhibit good light‐harvesting efficiencies under both sunlight and indoor light, with efficiencies up to 7.92 % under one sun (AM 1.5G). When operated under indoor light, the efficiency could be boosted to 27.76, 28.74, and 30.45 % under 600, 1000, 2500 lux
制备了一系列掺有喹喔啉或喹喔啉基部分的Y形敏化剂,并将其应用于染料敏化太阳能电池(DSSC)。通过引入喹喔啉类官能团,可以提高吸收消光系数。通过在供体(D)和π桥(DA–π–A)之间引入一个额外的受体基团(A),并在喹喔啉部分的各个位置引入供电子取代基,可以修饰分子结构。发现某些染料及其混合物在日光和室内光下均表现出良好的集光效率,在一种阳光下(AM 1.5G)的效率高达7.92%。在室内光线下操作时,在600、1000和2500 lux照度下,效率可以分别提高到27.76%,28.74和30.45%。2面。
