17% efficiency for linear-shaped ADA-type nonfullerene acceptors enabled by 3D reticulated molecular packing

Enhancing Photovoltaic Performance of Ladder‐Type Heteroarene‐Based Electron Acceptors by Modulating Molecular Packing†

“…[ 21 ] In such A‐D‐A‐structured NFAs, the fused‐ring donor cores undoubtedly play a critical role since they can directly influence most of the PSC‐related physical and electrochemical properties of the resulting NFAs, such as optical bandgaps, energy levels, and inter/intramolecular interactions. [ 22‐26 ] Actually, the structural flexibility of NFAs stems mainly from the rich diversity of donor cores. [ 27‐31 ] Both symmetric and asymmetric donor cores can be used to construct efficient A‐D‐A‐type NFAs.…”

The effect of the third component on high performance ternary organic solar cells: A review

“…[7][8][9] OSCs can be mounted on wearable and portable electronics and can be folded into smaller sizes for easier transport and storage. [10][11][12][13] In addition, OSCs also have higher plasticity and can be more easily customized to meet specific application needs. 14 In-depth research on the development of active layer materials, morphology adjustment, photophysics, and device processing technology has continuously made new progress.…”

In addition, OSCs also have higher plasticity and can be more easily customized to meet specific application needs 14 .…”

A narrow band gap non-fullerene electron acceptor based on a dithieno-3,2-b:2′,3′-dlpyrrole unit for high performance organic solar cells with minimal highest occupied molecular orbital offset

“…Hence, in order to further improve the PCEs of OSCs based on A–D–A type NFSMAs, many material strategies of A–D–A type NFSMAs have been proposed in recent years. 22–27…”

“…Hence, in order to further improve the PCEs of OSCs based on A-D-A type NFSMAs, many material strategies of A-D-A type NFSMAs have been proposed in recent years. [22][23][24][25][26][27] Among these material design strategies, designing A-D-A type NFSMAs with a narrow band gap is an effective strategy to extend the absorption spectrum and increase the short circuitcurrent (J sc ), and thus improve the PCEs of OSCs based on A-D-A type NFSMAs. [28][29][30][31][32][33] In general, enhancing the electrondonating ability of the donor fused-ring core of the A-D-A type NFSMAs can improve the enhanced intramolecular-charge transfer (ICT) effect, and thereby reduce the band gap of the A-D-A type NFSMAs.…”
