Org. chromophores were synthesized to study the benefits of structural vs. spectral properties as well as the absorption properties and solar cell performance with an unsym.-substituted chromophore. High Voc was found for the structurally sym. dye which al ...
Tandem solar cells using different bandgap absorbers allow efficient photovoltaic conversion in a wide range of the solar spectrum. The optical gaps of the dye-sensitized solar cell and the Cu(In,Ga)Se2 solar cell are ideal for application in double-junctio ...
In this letter, we report on an efficient org. tandem solar cell combining a solid state dye-sensitized with a ZnPc / C 60 -based, vacuum deposited bulk heterojunction solar cell. Due to an effective serial connection of both subcells and to the complement ...
Perhaps the largest challenge for our global society is to find ways to replace the slowly but inevitably vanishing fossil fuel supplies by renewable resources and, at the same time, avoid negative effects from the current energy system on climate, environ ...
Ionic liquids have been identified as a new class of solvent that offers opportunities to move away from the traditional solvents. The physical-chemical properties of ionic liquids can be tuned and controlled by tailoring their structures. The typical prop ...
In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...
The solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...
Tandem solar cells, in which two individual cells are stacked on top of each other, offer the potential to increase the efficiency significantly compared to a single cell on the same area. To reach maximum efficiency, each cell in the stack must have a dis ...

A small org. sensitizer, the polyene-diphenylaniline dye D5, was compared with the std. sensitizer N719 [Ru(dcbpy)2(NCS)2] in a dye-sensitized solar cell investigation. In solar cells with relatively thin layers of mesoporous TiO2 (
