Keywords:
inductive-resonance energy transfer, organic dyes, solar cell, photovoltaic parametersAbstract
Singlet-singlet energy transfer from Coumarine-7 to myristinate Rhodamine 6G was studied. The band of sensibilized fluorescence of acceptor molecules appears in long-wave part of spectrum upon the expiation in the absorption band of donor, meanwhile intensity of donor fluorescence is quenched. The study of influence of process of energy transfer of electron excitation on parameters of Gratzel cells, sensitized by donor and acceptor molecules. It was cleared, that at co-sensitization of electrodes of solar cells by donor and acceptor molecules, the increasing of value of parameters of current, which is generated at conversion of light into electrical energy. The presence of process of energy transfer is not affect on parameters of voltage of electrolytic solar cell. The optimal concentration of donor molecules was found equal to 10-4 mol/l, and gives great contribution in process of conversion of absorbed light into electrical energy.References
