Highly efficient fullerene and non-fullerene based ternary organic solar cells incorporating a new tetrathiocin-cored semiconductor

Organic photovoltaic (OPV) devices based on nanocomposites of π-conjugated semiconductors are a prospective solar cell technology and have attracted considerable attention due to unprecedented attributes such as printability, foldability, portability, wearability, semi-transparency and amenability to cost-effective large area fabrication. Extensive and focussed research to enhance the power conversion efficiency (PCE) of organic solar cells have led to the development of highly efficient bulk heterojunction (BHJ) single and multijunction organic solar cells with PCEs > 15%.*

In the paper “Highly efficient fullerene and non-fullerene based ternary organic solar cells incorporating a new tetrathiocin-cored semiconductor” Lethy Krishnan Jagadamma, Rupert G. D. Taylor, Alexander L. Kanibolotsky, Muhammad Tariq Sajjad, Iain A. Wright, Peter N. Horton, Simon J. Coles, Ifor D. W. Samuel and Peter J. Skabara present a dual-chain oligothiophene-based organic semiconductor, EH-5T-TTC.*

Detailed characterisation of the ternary blend systems as presented in the paper implies that the ternary small molecule EH-5T-TTC functions differently in polymer: fullerene and polymer: non-fullerene blends and has dual functions of morphology modification and complementary spectral absorption.*

To understand the differences in recombination dynamics of the blends containing EH-5T-TTC and fullerene/non-fullerene acceptors, detailed morphological characterisation was performed using atomic force microscopy (AFM).*

NANOSENSORS™ PointProbe® Plus PPP-NCSTR silicon AFM probes with typical force constant of 7.4 Nm−1 were used for the AFM height images presented in the paper.
