摘要
小分子有机光伏材料因其结构确定、易于修饰、易于提纯的特性受到了广泛的关注,器件效率达到10%。我们以双巯基噻吩基取代的苯并二噻吩(BDT)单元为核,设计并合成了两种A-D-A型小分子供体材料,通过改变末端受体单元,研究了材料结构对光谱吸收、HOMO和LUMO能级、活性层形貌以及光伏表现的影响。以这两种小分子为供体材料,PC_(71)BM为受体材料制备的本体异质结太阳能电池效率分别为4.31%和1.88%。
Small molecule(SM) for organic solar cells has drawn great attention due to the advantages of defined structure, easy modification and purification. Here we report the design and synthesis of two new A-D-A type small molecule donors based on dialkylthio-substituted thienyl-benzodithiophene. With the replacement of ending group, the relationships between material structure and absorption, HOMO and LUMO level, morphology and device performance are carefully investigated. Bulk heterojunction soalr cells fabricated with SM donor and PC71 BM acceptor performed a power convert efficiency of 4.31% and 1.88%.
