Electron-donor function of methanofullerenes (MFs) in bulk heterojunction systems is demonstrated by the combination of MFs with the electron-transporting π-system that has a much higher electron affinity than MFs.
A chemical model of deterioration of a bulk heterojunction organic solar cell containing a photooxidized product of 1,4-bis(dimethylphenylsilylmethyl)[60]fullerene suggests that molecular oxygen degrades device performance by two mechanisms.
We have studied the time-dependent charge transfer emission in a photovoltaic device made of blend poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclo-penta[2,1-b;3,4-b’]-dithiophene)-alt-4,7-(2,1,3 benzothiadiazole)] and [6,6]-phenyl C61-butyric acid methyl ester, system showing low band-gap suitable as absorber for bulk-heterojunction solar cells. find short-lived component (∼1 ns) no evidence long-liv...
The introduction of a low band-gap oligomer, oligo(benzo[1,2,5]thiadiazole-alt-3,3'''-dihexylquaterthiophene) (BT4T) improved the performance of P3HT:PCBM bulk heterojunction organic photovoltaic cells due to improved UV-vis absorption and increased P3HT crystallinity.
