一种染料光敏化剂及其制备方法和应用
摘要：
本发明属于太阳能电池技术领域，尤其涉及一种染料光敏化剂及其制备方法和应用。本发明提供的染料光敏化剂具有式(I)结构；式(I)中，A为具有式(a)或式(b)结构的取代基；E为具有式(c)或式(d)结构的取代基；其中，R1、R’1和R3分别独立地选自H、C1～C36烃基或C1～C36烷氧基取代的烃基；R2、R’2、R4、R5和R’5分别独立地选自C1～C36烃基或C1～C36烷氧基取代的烃基；R6和R7分别独立地选自H、F、C1～C36烃基或C1～C36烷氧基取代的烃基；x，y分别独立为0或1。实验结果表明，采用本发明提供的染料光敏化剂制备的染料敏化太阳能电池的光电转换效率最高可达13％，属目前国际领先水平。
摘要（英）：

The invention belongs to the technical field of solar cells and particularly relates to a dye photosensitizer as well as a preparation method and an application thereof. The dye photosensitizer has a structure shown in a formula (I), wherein in the formula (I), A is a substituent having a structure shown in a formula (a) or a formula (b); E is a substituent having a structure shown in a formula (c) or a formula (d); R1, R'1 and R3 are independently selected from H, C1-C36 alkyl groups or C1-C36 alkoxy group substituted alkyl groups respectively; R2, R'2, R4, R5 and R'5 are independently selected from C1-C36 alkyl groups or C1-C36 alkoxy group substituted alkyl groups respectively; R6 and R7 are independently selected from H, F, C1-C36 alkyl groups or C1-C36 alkoxy group substituted alkyl groups respectively; x and y are 0 or 1 independently respectively. Experiment results prove that the photoelectric conversion efficiency of a dye sensitized solar cell prepared from the dye photosensitizer can reach 13% to the maximum and is on the international advanced level at present.
