π-conjugated polyelectrolytes (CPEs) have been commonly used as an interfacial layer for polymer solar cells (PSCs) over the past decade. In the CPEs, polymers which consist of fluorene derivatives as the backbone are usually applied to PSCs. To improve the photovoltaic properties, we synthesized CPEs having electron rich moiety, phenothiazine, and compared to those of the fluorene homopolymer. From the density functional theory (DFT) and ultraviolet photoelectron spectroscopy (UPS) data, we also confirmed that conformations of synthesized CPEs have influence on the work function of metal and morphology of film. In this presentation, we will report the synthesis, conformations of CPEs, and photovoltaic properties. |
