摘要

Using poly (3,4-ethylene-dioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) as an effective hole collecting layer, high-efficiency PEDOT:PSS/n-Si hybrid solar cells are fabricated and a power conversion efficiency (PCE) of 12.13% is obtained. After being treated by HNO3 vapor, the PCE value of PEDOT:PSS/n-Si hybrid solar cells enhances from 12.13% to 13.44%. NO2 gas molecules in HNO3 vapor play a significant doping role in raising the PCE of solar cells. As the doping level raises, NO2 would get more electrons from PEDOT and lead to the increase of hole carriers in the films, which improves the polymer film’s conductivity and PCE of solar cells.

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.
