Body centered non-fullerene acceptors substitution on triangular shaped Sub-phthalocyanines (SubPcs) based A-D-A organic solar cells: A step toward new strategies for better performances

Unveiling the influence of end-capped acceptors modification on photovoltaic properties of non-fullerene fused ring compounds: a DFT/TD-DFT study

“…An efficient approach to address the current energy problem is to utilize renewable and environment friendly energy sources such as solar energy to replace polluting fossil fuels. 1 The OSCs have attracted signicant attention over inorganic and conventional silicon-based solar cells, owing to their advantages such as mechanical exibility, low-cost and light-weight. [2][3][4][5] Some OSCs used fullerene-based acceptors which exhibit considerable advantages with almost 10% power conversion efficiency (PCE).…”

Octupole moment driven free charge generation in partially chlorinated subphthalocyanine for planar heterojunction organic photodetectors

“…Usually, C 60 is the most widely employed electron acceptor in both PHJ and BHJ OPDs. However, several studies have highlighted the potential of subphthalocyanines (SubPc) derivatives as alternative acceptors, with the particular benefit of stronger and narrower bandwidth light absorption 4,5 . Moreover, SubPc halogenation can tune the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) levels for device optimisation and potentially suppress recombination processes 6 .…”
