제목 | Conjugated water/alcohol soluble polyelectrolytes with one-atom variation (O, S, Se) as hole transporting layer for organic photovoltaics |
초록 | To improve the power conversion efficiencies(PCEs) of PSCs, the control of an active layer/electrode interface to form an Ohmic contact is one of the pivotal factors. Conjugated water/alcohol soluble polymers that consist of a conjugated main chain and a polar/ionic side chain have received growing attention because of their outstanding intrinsic optoelectronic properties, good stability and unique solubility. In this work, we present the synthesis and characterization of new conjugated polyelectrolytes(CPEs) containing aromatic five-membered heterocyclic compounds. Replacement of the sulfur atom of thiophene by the oxygen and selenium atoms is expected to alter the electronic structure of the corresponding polymers. We study the effects of the electronic properties at the interface between the anode and the active layer. An increase in a dipole moment leads to decrease the work function of ITO electrodes and the surface potential between the active layer and HTL effectively. |
