A light harvesting array useful for the manufacture of devices such as solar cells comprises: (a) a first substrate comprising a first electrode; and (b) a layer of light harvesting rods electrically coupled to the first electrode, each of the light harvesting rods comprising a polymer of Formula I:
X1&Parenopenst;Xm+1)m (I)
wherein m is at least 1, and may be from two, three or four to 20 or more; X1 is a charge separation group (and preferably a porphyrinic macrocycle, which may be one ligand of a double-decker sandwich compound) having an excited-state of energy equal to or lower than that of X2, and X2 through Xm+1 are chromophores (and again are preferably porphyrinic macrocycles).
一种用于制造太阳能电池等设备的光收集阵列,包括:(a)第一衬底,包括第一电极; 和(b)与第一电极电性耦合的光收集棒层,每个光收集棒包括式I的聚合物:X1&Parenopenst;Xm+1)m (I),其中m至少为1,可以为2、3、4到20或更多; X1是一个电荷分离基团(最好是
卟啉宏环,可以是双层三明治化合物的一个
配体),其激发态能量等于或低于X2,而X2到Xm+1是色团(同样最好是
卟啉宏环)。
