Smart Ternary Strategy in Promoting the Performance of Polymer Solar Cells Based on Bulk-Heterojunction or Layer-By-Layer Structure

Wenjing Xu et al.

Summary: The study explores the use of a ternary strategy to improve the power conversion efficiency of polymer solar cells (PSCs) by incorporating three different materials. Results show that the ternary PSCs exhibit significantly higher PCE compared to binary PSCs, mainly due to an increase in fill factor.

End-Group Functionalization of Non-Fullerene Acceptors for High External Quantum Efficiency over 150 000% in Photomultiplication Type Organic Photodetectors

Seongwon Yoon et al.

Summary: This study explores the impact of end-functionalization of a novel extended aromatic fused-ring non-fullerene acceptor on carrier trap/transit time in PM-OPDs. It is found that fluorination of the NFA can enhance the deepest lowest unoccupied molecular orbital level and non-isotropic molecular ordering, leading to longer carrier lifetime. Additionally, fluorination of the NFA can improve its hydrophobic nature, allowing for efficient injection barrier thinning and maximizing hole injection efficiency from the cathode.

Over 17% Efficiency of Ternary Organic Photovoltaics Employing Two Acceptors with an Acceptor-Donor-Acceptor Configuration

Xiaoling Ma et al.

Summary: Ternary organic photovoltaics constructed with one wide-band-gap donor PM6 and two A-D-A-type acceptors (M-series M36 and MQ5) achieved a power conversion efficiency of 17.24%. The optimization of ternary OPVs was attributed to the complementary absorption spectra of M36 and MQ5, maximizing photon harvesting and charge transport in the active layers. Introducing an appropriate amount of MQ5 resulted in more than an 8.8% improvement in PCE and demonstrated the huge potential of A-D-A-type materials in constructing highly efficient OPVs using a ternary strategy.

Summary: Efficient ternary blend organic photovoltaic devices can be achieved by utilizing D18-Cl:Y6 host system and adding star polymer donor PM6. The incorporation of PM6 in active layers not only enhances the power conversion efficiency but also decreases the trap density, leading to weakened charge recombination in ternary blend active layers. The compatibility and similar HOMO levels between D18-Cl and PM6 enable the formation of efficient hole transport in ternary blend active layers.

Highly Sensitive Narrowband Photomultiplication-Type Organic Photodetectors Prepared by Transfer-Printed Technology

Zijin Zhao et al.

Summary: Narrowband photomultiplication-type organic photodetectors (PMOPDs) were developed using poly(3-hexylthiophene-2,5-diyl) (P3HT) as the optical field adjusting (OFA) layer and transfer-printed P3HT:[6,6]-phenyl-C-71-butyric acid methyl ester (PC71BM) as the photomultiplication (PM) layer. The addition of a wide bandgap polymer poly[N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] (P-TPD) into the OFA layer significantly enhanced the device performance, with improved hole tunneling injection and transport efficiency attributed to increased trapped electron density near the Al electrode and improved hole mobility. The promising potential of PMOPDs in imaging applications was demonstrated through clear imaging without the need for current preamplifiers.
