有机染料DN-F系列

  在过去的几年里，有机光敏染料因生产原料易得，分子结构设计多样化，易于回收以及大规模生产的经济节约性而被广泛应用于染料敏化太阳能电池的研究。尤其是在2010年，Anders Feldt教授的科研团队成功地将有机染料与多吡啶钴这一单电子氧化还原电对相结合，报道了其优异的光电转换效率（J. Am. Chem. Soc., 2010, 132 (46), pp 16714–16724），自此，人们对有机光敏染料的研究兴趣进一步增强。瑞典Dyenamo公司现推出5款标准有机宽光谱吸收染料和一款有机红外吸收染料供您选择。
DN-F系列：宽光谱吸收有机染料
     2012年，DN-F04（D35）染料在全球范围内已被确立为基于有机光敏染料的太阳能电池研究的参比染料，这一参比染料的确立具有非常重要的研究意义。DN-F05染料(亦称为D35CPDT)与DN-F04（D35）相比，其在红外区域的光谱响应增强。另外，DN-F05染料与DN-F05Y（Y123）染料非常相似，已经达到了10%的光电转化效率(Energy Environ. Sci., 2011, 4, 4921–4924. DOI: 0.1039/C1EE02389F)。此外，DN-F05在高温下表现出了优异的稳定性（Jian et al., Solar Energy Materials and Solar Cells (2013，http://dx.doi.org/10.1016//j.solmat.2013.04.017)。染料DN-F01，DN-F02和 DN-F03为π共轭桥基链不断增长的一系列染料。其中DN-F01是结构最简单的供-吸体系染料，具有较高的氧化电位。DN-F03 (D5)则是一个效率较高，应用范围较广的有机染料。
