Abstract

A poly(3,3-diethyl-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepine) (PProDOT-Et2) counter electrode was incorporated in a plastic dye-sensitized solar cell (DSSC) to substitute for Pt electrode. The surface morphology and I−/I3− redox behaviors based on PProDOT-Et2 and sputtered-Pt electrodes were characterized, and their performances as counter electrodes in the plastic-DSSCs were compared. Cells fabricated with a PProDOT-Et2 counter electrode showed a higher conversion efficiency of 5.20% compared with cell fabricated with sputtered-Pt (5.11%) electrodes under the illumination of 100 mW cm−2. This enhancement was attributed to the increase in the effective surface area and good catalytic properties of PProDOT-Et2 for I3− reduction.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
