Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 3681-71-8, Name is cis-3-Hexenyl acetate, SMILES is CC(OCC/C=CCC)=O, belongs to esters-buliding-blocks compound. In a document, author is Cuesta, Virginia, introduce the new discover, HPLC of Formula: C8H14O2.
Reducing Energy Loss in Organic Solar Cells by Changing the Central Metal in Metalloporphyrins
The effect of central donor core on the properties of A-pi-D-pi-A donors, where D is a porphyrin macrocycle, cyclopenta[2,1-b:3,4-b’]dithiophene is the pi bridge, and A is a dicyanorhodanine terminal unit, was investigated for the fabrication of the organic solar cells (OSCs), along [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as electron acceptor. A new molecule consisting of Ni-porphyrin central donor core (VC9) showed deep HOMO energy level and OSCs based on optimized VC9:PC71BM realized overall power conversion efficiency (PCE) of 10.66 % [short-circuit current density (J(SC))=15.48 mA/cm(2), fill factor (FF)=0.65] with high open circuit voltage (V-OC) of 1.06 V and very low energy loss of 0.49 eV, whereas the Zn-porphyrin analogue VC8:PC71BM showed PCE of 9.69 % with V-OC of 0.89 V, J(SC) of 16.25 mA/cm(2) and FF of 0.67. Although the OSCs based on VC8 showed higher J(SC) in comparison to VC9, originating from the broader absorption profile of VC8 that led to more exciton generation, the higher value of PCE of VC9 is owing to the higher V-OC and reduced energy loss.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3681-71-8 is helpful to your research. HPLC of Formula: C8H14O2.
