experimental data analysis and theoretical simulation. The polymers possess highly planar backbones, broad Vis/NIR absorption bands, suitable frontier molecular orbital energies, and low band gaps ranging from 1.3 to 1.8 eV. The power conversion efficiencies of their photovoltaic devices are about 1 %. Introducing longer alkyl side chains into a polymer can bring about a better film-forming ability and improve
作为稠环共轭单元,三苯二恶嗪已应用于聚合物太阳能电池的两系列无噻吩共轭聚合物中。聚合物是通过多步合成路线合成的,取代基对反应物的反应性有很大的影响。通过实验数据分析和理论模拟,详细研究了聚合物结构之间的关系以及热,光学和电化学性能。该聚合物具有高度平坦的骨架,宽的Vis / NIR吸收带,合适的前沿分子轨道能以及1.3至1.8 eV的低带隙。他们的光伏器件的功率转换效率约为1%。
