Abstract Organic materials are receiving more attention in the solar cell due to their better solution process, controllable synthesis, tunable chemical and physical properties. However, the focus problem of compatibility and aggregation is to be solved urgently in organic materials, which inevitably limits them widely application. To this end, an inorganic–organic hybrid materials with wide-band absorption is designed and prepared, that incorporates octavinyl-polyhedral oligomeric silsesquioxane with 6-bromoquanaldine to produce H1, then reacts with squaric acid to design H2, which efficiently avoids the fluorescence quenching due to the steric hindrance. The electrochemical results shows that the energy level of H2 is match well with the commercial dye N719. Hence it shows a better photovoltaic performance based on dye-sensitized solar cell, along with power conversion efficiency up to 7.73% when it is co-sensitized with N719. The hybrid system exhibits good performances in solar cell and long-term stability.

一种制备和应用具有宽带吸收的方酸纳米杂化物的简便策略

摘要 有机材料由于具有较好的溶解过程、可控合成、可调节的化学和物理性质，在太阳能电池中受到越来越多的关注。然而，有机材料中的相容性和聚集问题是亟待解决的热点问题，这不可避免地限制了它们的广泛应用。为此，设计并制备了一种具有宽带吸收的无机-有机杂化材料，该材料将八乙烯基-多面体低聚倍半硅氧烷与 6-溴喹啉结合生成 H1，然后与方酸反应生成 H2，有效避免了荧光猝灭由于位阻。电化学结果表明，H2 的能级与市售染料 N719 匹配良好。因此它显示出基于染料敏化太阳能电池的更好的光伏性能，与 N719 共敏时，功率转换效率高达 7.73%。该混合系统在太阳能电池方面表现出良好的性能和长期稳定性。
