Exploring ternary organic photovoltaics for the reduced nonradiative recombination and improved efficiency over 17.23% with a simple large-bandgap small molecular third component

Huanran Feng et al.

Summary: The ternary strategy is an effective method to improve the power conversion efficiency of organic photovoltaic cells, by introducing a third component to reduce energy loss. The introduction of the simple molecule BR1 has been shown to enhance the performance of PM6:Y6-based OPVs and increase the PCE of the photovoltaic cells.

Slow Relaxation of Photogenerated Charge Carriers Boosts Open-Circuit Voltage of Organic Solar Cells

Tanvi Upreti et al.

Summary: Research shows that the open-circuit voltage of organic solar cells is not caused by the thermalization of photogenerated charge carriers, but rather by incomplete relaxation in the disorder-broadened density of states, resulting in a V-OC 0.1-0.2V higher than it would be in thermodynamic equilibrium. This suggests that organic solar cells function as nonequilibrium devices, harvesting excess photon energy in the form of an enhanced V-OC.

ITIC derivative acceptors for ternary organic solar cells: fine-tuning of absorption bands, LUMO energy levels, and cascade charge transfer

Seungyun Baik et al.

Summary: By designing and synthesizing ITIC derivatives, the photoelectric efficiency of ternary organic solar cells (TOSC) can be improved. In the PBDB-T:ITIC:A(2)-based ternary system, adding ITIC derivatives can enhance the photoelectric efficiency and improve open-circuit voltage, short-circuit current density, and fill factor.

Charge Transfer Mechanisms Regulated by the Third Component in Ternary Organic Solar Cells

Ming-Yang Li et al.

Summary: This study investigates the influence of introducing a third component (D-2) in ternary organic solar cells (T-OSCs) on the charge transfer mechanism. The results indicate that factors such as molecular weight and oscillator strength of D-2 affect the selection of charge transfer pathways, providing important insights for improving the efficiency of T-OSCs.

Mode of action of the third component in ternary organic photovoltaic blend PBDB-T/ITIC:PC70BM revealed by EPR spectroscopy

A. A. Popov et al.

Summary: The difference in charge generation and recombination processes between highly efficient ternary OPV blend PBDB-T/ ITIC:PC70BM and the corresponding binary blends PBDB-T/ITIC and PBDB-T/PC70BM was traced using LEPR and ESE techniques. Addition of PC70BM was found to improve charge transport and reduce geminate recombination in the ternary blends.

High-efficiency organic solar cells with low voltage loss induced by solvent additive strategy

Jiali Song et al.

Summary: The use of a solvent additive strategy with diiodomethane (DIM) instead of 1,8-diiodooctane (DIO) has been effective in reducing high voltage loss (V-loss) in organic solar cells (OSCs), leading to improved power conversion efficiency (PCE) and open-circuit voltage (V-oc). The approach has also been successfully applied to different blends, achieving high PCEs with reduced V-loss.
