Single-layered organic photovoltaics with double cascading charge transport pathways: 18% efficiencies

Ming Zhang et al.

Summary: By using quaternary blends, double cascading energy level alignment is achieved in bulk heterojunction organic photovoltaic active layers, optimizing light absorption, carrier transport, and charge-transfer state energy levels for higher power conversion efficiencies. The chemical structures of donors and acceptors allow control over electronic structure and charge-transfer state energy levels, enabling manipulation of hole-transfer rates, carrier transport, and non-radiative recombination losses.

A History and Perspective of Non-Fullerene Electron Acceptors for Organic Solar Cells

Ardalan Armin et al.

Summary: Organic solar cells have evolved from relying on fullerenes as acceptors to the emergence of non-fullerene acceptors (NFAs) which have significantly improved cell efficiencies. However, NFAs challenge the traditional understanding of organic solar cell operation, requiring rethinking of morphology, charge generation, and recombination.

Layer-by-Layer Processed Ternary Organic Photovoltaics with Efficiency over 18%

Lingling Zhan et al.

Summary: This study proposes and demonstrates a method to optimize the morphology of the active layer in organic photovoltaic devices by combining the layer-by-layer (LbL) procedure and the ternary strategy. By adding an asymmetric electron acceptor to the binary donor:acceptor host, a vertical phase distribution is formed, leading to improved efficiency in OPV devices.

Solvent Annealing Enables 15.39% Efficiency All-Small-Molecule Solar Cells through Improved Molecule Interconnection and Reduced Non-Radiative Loss

Jinfeng Ge et al.

Summary: The study found that solvent annealing with solvents of good solubility is more beneficial for molecular migration and crystallization than thermal annealing, leading to improved efficiency and performance of solar cells. CS2 solvent is better at optimizing donor domain size, improving molecular interconnection, reducing trap states, and decreasing non-radiative recombination. CS2 solvent treatment also helps enhance overall solar cell performance by reducing non-radiative recombination and improving efficiency.

Exploring the Charge Dynamics and Energy Loss in Ternary Organic Solar Cells with a Fill Factor Exceeding 80%

Yihan Zeng et al.

Summary: Ternary architecture shows potential in enhancing power conversion efficiencies of organic solar cells, with the fill factor generally below 78%. Studies indicate that effective exciton dissociation, enhanced charge transport, and suppressed recombination are crucial for achieving high-fill factor and low-energy loss in ternary cells.
