Hybrids based on a dibenzosuberene core bearing a spiro-fluorene junction at the C-5 position and with amino donor and β-thiophenyl-α-cyanoacrylic acid acceptor groups at C-3 and C-7, respectively, serve as new organic sensitizer materials for solar cell applications. Solar cell devices based on these materials show a conversion efficiency (η) of up to 6.1% (Voc = 697 mV, Jsc = 12.2 mA cm−2, FF = 0.72) under AM 1.5 G conditions. The best IPCE values exceed 75% within the 450–550 nm absorption range.
基于二苯并苏伯烯核心的杂合材料,在C-5位具有螺旋荧光苯连接,C-3和C-7位分别带有氨基供体和β-噻吩基-α-氰基丙烯酸受体基团,作为新型有机敏化剂材料用于太阳能电池应用。基于这些材料的太阳能电池设备在AM 1.5 G条件下显示出高达6.1%的转换效率(η)(开路电压Voc = 697 mV,短路电流密度Jsc = 12.2 mA cm−2,填充因子FF = 0.72)。最佳的光电流转换效率(IPCE)值在450–550 nm吸收范围内超过75%。
