Abstract Benefiting from the photovoltaic material innovation and delicate device optimization, high‐efficiency solar cells employing polymeric materials are thriving. Reducing gap of cost, efficiency, stability is critical challenge faced by emerging such as organics, quantum dots perovskites. Poly(3‐alkylthiophene) demonstrates great potential in organic dot active layer or hole transport due to its large scalability, excellent photoelectric performance, favorable hydrophobicity. The present low efficiency insufficient stability, restrict commercial application. In this work, a facile strategy blending two simple polythiophenes put forward manipulate film microstructure enhance thermal cells. introduction P3PT can improve power conversion (PCE) benchmark cost‐effective blend P3HT:O‐IDTBR 7.41%, developed ternary also exhibit increased stability. More strikingly, with dual‐polythiophene achieve highest PCE 10.51%, which among topmost efficiencies for dots/polythiophene Together, work provides an effective route simultaneously optimize

Series of bulk heterojunction (BHJ) and layer‐by‐layer (LbL) all‐polymer solar cells (APSCs) were prepared with polymer PM6 as donor PY‐DT acceptor based on conventional inverted configuration. Benefiting from the sequential deposition strategy, good vertical phase separation more ordered molecular arrangement can be formed in LbL APSCs. The APSCs exhibit an optimized power conversion efficiency (PCE) 17.24% a relatively large short circuit current density 23.83 mA cm −2 fill factor 74.60%, photogenerated excitons near indium tin oxide electrode efficiently utilized through energy transfer to self‐absorption effect for its long exciton diffuse distance. PCE is higher than 16.72% BHJ APSCs, 14.59% 12.41% rather low further indicates that should play vital role determining performance This work provides insights carrier dynamic process sequentially deposited active layer, providing guidance preparing efficient

Oligomerized Fused‐Ring Electron Acceptors for Efficient and Stable Organic Solar Cells

Angewandte Chemie, Год журнала: 2023, Номер 135(46)

Опубликована: Июль 12, 2023

Abstract Organic solar cells (OSCs) have attracted wide research attention in the past decades. Very recently, oligomerized fused‐ring electron acceptors (OFREAs) emerged as a promising alternative to small‐molecular/polymeric acceptor‐based OSCs due their unique advantages such well‐defined structures, batch reproducibility, good film formation, low diffusion coefficient, and excellent stability. So far, rapid advances been made development of OFREAs consisting directly/rigidly/flexibly linked oligomers fused ones. In this Minireview, we systematically summarized recent progress OFREAs, including structural diversity, synthesis approach, molecular conformation packing, long‐term Finally, conclude with future perspectives on challenges be addressed potential directions. We believe that Minireview will encourage novel for OSC applications.

We prepared ternary organic solar cells (OSCs) by incorporating the medium wavelength absorption polymer PSEHTT into PM6:L8-BO binary system. The power conversion efficiency (PCE) is improved from 15.83% to 16.66%. Although fill factor (FF) slightly reduced, short-circuit current density (JSC) and open-circuit voltage (VOC) are significantly increased at same time. A small amount of has a broad spectrum in short region good compatibility with PM6, which conducive fine-tuning photon collection improving JSC. In addition, highest occupied molecular orbital (HOMO) energy level deeper than that broadens optical bandgap.
