Intrinsic efficiency limits in low-bandgap non-fullerene acceptor organic solar cells

Safakath Karuthedath et al.

Summary: In bulk heterojunction organic solar cells based on low-bandgap non-fullerene acceptors, ultrafast donor-to-acceptor energy transfer precedes hole transfer, and an ionization energy offset of about 0.5 eV is required for efficient charge separation.

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.

Excitons Dominate the Emission from PM6:Y6 Solar Cells, but This Does Not Help the Open-Circuit Voltage of the Device

Lorena Perdigon-Toro et al.

Summary: The research findings show that the radiative recombination in the blend of non-fullerene acceptors with donor polymer is mainly due to the re-occupation and decay of Y6 singlet excitons, contributing less than 1% to total recombination. The open-circuit voltage of the blend is determined by the energetics and kinetics of the charge-transfer state, rather than the radiative recombination of free charges caused by the Y6 singlet excitons.

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.
