The present invention relates to a compound of formula (I) based on quinozilino acridine and used as hole transporting and light absorbing material in a photovoltaic device, in particular in a solid state solar cell. ...

The development of metal-free organic sensitizers is a key issue in dye-sensitized solar cell research. We report successful photovoltaic conversion with a new class of stable tetrathiafulvalene derivatives, showing surprising electrochemical and kinetic p ...

Pivalic acid (PVA) was used as a new coadsorbent to dyesensitized solar cells (DSCs) to modify the interface between the TiO2 films and electrolyte. The addition of PVA improved the light-to-electricity conversion efficiency of devices by 8% by enhancing t ...

The detailed synthesis and characterization of four ruthenium(II) complexes [RuLL(NCS)(2)] is reported, in which L represents a 2,2-bipyridine ligand functionalized at the 4,4 positions with benzo[1,2-b:4,5-b]dithiophene derivatives (BDT) and L is 2,2-bipy ...

A novel, asymmetric DPP bridge/core was synthesized and tested in DSC devices. By desymmetrising the DPP core/bridge, a remarkable IPCE of >80% and a maximum power conversion efficiency of 7.7% were achieved. With the use of a wide-bandgap co-sensitizer, 8 ...
