F-M is a non-fullerene acceptor that absorbs visible light, when used in a front cell paired with NIR absorbing rear cell, the resulted tandem organic solar cell gave a record energy conversion efficiency of 17.3%.Tandem Cell Device performance:ITO/ZnO/PFN-Br/PBDB-T:F-M/M-PEDOT/ZnO/PTB7- Th:O6T-4F:PC71BM/MoO3/Ag Voc=1.642 VJsc=14.35 mA/cm2FF=73.7% PCE=17.3%
General Description
Non-fullerene acceptors (NFAs) are currently a major focus of research in the development of bulk-heterojunction organic solar cells (OSCs). In contrast to the widely used fullerene acceptors (FAs), the optical properties and electronic energy levels of NFAs can be designed and readily tuned. NFA-based OSCs can also achieve greater thermal stability and photochemical stability, as well as longer device lifetimes, than their FA-based counterparts.Recent developments have led to a rapid increase in power conversion efficiencies for NFA OSCs, with values now exceeding 15% in a single junction cell, and >17% for a tandem cell, demonstrating the viability of using NFAs to replace FAs in next-generation high-performance OSCs.
Check Digit Verification of cas no
The CAS Registry Mumber 71481-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,8 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71481-64:
(7*7)+(6*1)+(5*4)+(4*8)+(3*1)+(2*6)+(1*4)=126
126 % 10 = 6
So 71481-64-6 is a valid CAS Registry Number.

The isomeric .+ Hydrogen-Bridged Radical Cations .+, .+, and .+: Theory and Experiment

From combination of mass spectrometry based experiments and high-level molecular orbital theory calculations, three new, thermodinamically stable isomers of ionized ethylene glycol, .+ (1), have been identified.These are the hydrogen-bridged radical cations .+ (2), .+ (3), and .+ (4); a fifth isomer, also H-bridged, .+, has been previously reported.The ion .+ (3) was experimentally identified (via a double collision experiment) as the stable ion formed by loss of CO from ionized methyl glycolate, whereas 2 was proposed to be a long-lived, rearranged form of ionized glycol, 1.The common unimolecular dissociations of 2 and 3 into CH3OH2+ and HCO0 were associated with energy barriers attributed to their rearrangement into (energy-rich) ions of structure 4, from which the dissociation proceeds by direct bond cleavage.This study underlines the important role that -H-O- hydrogen-bridged radical cations can play in the gas-phase ion chemistry of oxigencontaining compounds and is another example of the succesful combination of theory and experiment in gas-phase ion chemistry.
