Herein, we demonstrate a kind of high performance semi-transparent polymer solar cell (STPSC) with a significantly improved color rendering index (CRI) and power conversion efficiency (PCE) by introducing one-dimensional photonic crystals (1DPCs), which are intentionally designed to strongly reflect the pristine weak absorbed light to flatten the concavo-convex transmittance spectrum of STPSCs. The transmitted light from the STPSC device with 4 pairs of 1DPCs under AM 1.5G illumination shows extraordinary color rendering capacities, which contribute an increased CRI from 79 to 91, combined with an enhanced PCE from 4.14% to 5.01% compared to devices without 1DPCs. The simultaneously improved optical and electrical performance suggests that STPSCs can provide a unique feature, which is suitable for building integrated photovoltaic applications.

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.
