The origin of the open-circuit voltage of polymer:fullerene solar cells in terms of donor/acceptor ground-state charge transfer complex formation
关键字：fullerene solar cells
In order to increase the efficiency of polymer:fullerene solar cells, understanding of the origin and ofthe fundamental limit of the open-circuit voltage (Voc) is crucial. In this work we demonstrate with thethermodynamic theory of&nbs...

High performance organic sensitizers based on 11,12-bis(hexyloxy) dibenzo[a,c]phenazine for dye-sensitized solar cells
关键字：organic sensitizers, dye-sensitized solar cells, 11,12-bis(hexyloxy) dibenzo[a,c]phenazine
Three new metal-free organic sensitizers containing 11,12-bis(hexyloxy) dibenzo[a,c]phenazine (BPz) units were synthesized and used for dye-sensitized solar cells (DSSCs). The broad absorption spectra indicate that the light harvesting abilities were enhanced by the introduction of the BPz unit in the p-conjugated space, which can also cause an anti-aggregation effect and the suppression of charge...

Efficient Metal-Free Organic Sensitizers Containing TetraphenylethyleneMoieties in the Donor Part for Dye-Sensitized Solar Cells
关键字：Donor–acceptor systems, Dyes/pigments, Sensitizers, Solar cells, Energy conversion
Two new propeller-shaped D-π-A organic sensitizers that contain two tetraphenylethylene (TPE) moieties in the donor part of the triphenylamine group have been designed and
characterized. These dyes are composed of the same donor and acceptor units with different aromatic units introduced through linkers between the donor and acceptor units. The dye-sensitized solar cells (DSCs) based on LI-31 wit...

New efficient dyes containing tert-butyl in donor for dye-sensitized solar cells
关键字：Tert-butyl, Triphenylamine, Anti-aggregation, Dye-sensitized solar cells, Sensitizers, Power conversion effciency
A series of D-pi-A organic sensitizers that contains two 4-tert-butylbenzene moieties in the donor part of triphenylamine group are designed and characterized. All these dyes comprise the same donor and acceptor units while the different aromatic units are introduced as linkers between the donor and acceptor units. It is found that the tuning of the HOMO and LUMO energy level can be conveniently...

New sensitizers bearing quinoxaline moieties as an auxiliary acceptor for dye-sensitized solar cells
关键字：Quinoxaline, Triphenylamine, Auxiliary acceptor,Dye-sensitized solar cells,Sensitizers,Power conversion efficiency
Two organic sensitizers (LI-40 and LI-41) containing 6,7-bis(hexyloxy)-2,3 dimethylquinoxaline unit and thiophene or furan as conjugated bridge were synthesized and utilized for dye-sensitized solar cells (DSSCs). The incorporation of quinoxaline unit brought about impressive changes in absorption spectra and energy levels, thus, enhanced the light-harvesting for photovoltaic conv...

Attempt to Improve the Performance of Pyrrole-Containing Dyes in Dye Sensitized Solar Cells by Adjusting Isolation Groups
关键字：pyrrole, isolation group, “H” type dyes, organic sensitizer, dye-sensitized solar cell
Four new pyrrole-based organic sensitizers with different isolation groups were conveniently synthesized and applied to dye sensitized solar cells (DSCs). The introduction of isolation group in the side chain could both suppress the formation of dye aggregates and electron recombination. Especially, when two pieces of D-π-A chromophore moieties shared one isolation group to c...
