液晶材料应用于有机半导体器件是近年该领域的研究热点之一.文章就液晶材料的半导体性质以及在有机光伏器件中的应用进行文献调研和述评.介绍了有机太阳能电池的基本原理、器件结构和液晶基本知识.分析了液晶分子自身作为给体或受体材料的研究现状,同时,对液晶材料作为添加剂在有机光伏器件中的应用进行了调查.结论认为,基于有机成分的液晶分子由于自身的有序性,在有机半导体器件制备过程中充当活性材料,有利于生成的激子解离和载流子的输运.作为添加剂,液晶分子参与诱导活性材料有序结晶,改善异质结界面及微观结构,同样提高激子解离效率和载流子输运能力.两者都能够有效提高有机光伏器件的转换效率.最后,对基于液晶材料的有机光伏器件的研究趋势进行了展望.
