The influence of a series of alkyl alcohols on the work function of PEDOT:PSS thin films is systematically investigated by Kelvin probe measurements. We show that the PEDOT:PSS work function can be increased stepwise from 5.2 eV for pristine PEDOT:PS

The determination of the optical constants n ( λ ) and k ( λ ) for organic bulk heterojunction (BHJ) active layers from standard solar cell measurements is presented. We show for a small molecule based as well as for polymer solar cells that the co

We have synthesized a series of new, polymethine chain extended merocyanine dyes 1–4 bearing varied acceptor units and an aminothiophene donor moiety. The optical and electronic properties of these new merocyanines have been studied in comparison w

Solution-processable polyazomethines containing thiophenes were synthesized and used as the donor material in bulk heterojunction solar cells. The blue polymers exhibited similar electrochemical properties to the benchmark P3HT with the advantage of

Small-molecule π-systems bearing donor (D) and acceptor (A) groups constitute an interesting class of dyes because of their tunable strong absorption, which covers the visible and near-infrared range. The dipolarity associated with D–A structures

We present a merocyanine:C 60 /zinc phthalocyanine:C 60 tandem solar cell, comprising two complementary absorbing bulk heterojunction subcells connected in series. High-efficiency devices were realized in a rather simple tandem setup, consisting of o

In order to be competitive on the energy market, organic solar cells with higher efficiency are needed. To date, polymer solar cells have retained the lead with efficiencies of up to 8%. However, research on small molecule solar cells has been catchi

We present the development of highly efficient merocyanine solar cells at the example of the dye MD376. Due to their unique processing flexibility, merocyanines have been applied in solution- as well as vacuum-processed organic photovoltaics. In full

A novel bis(merocyanine) dye has been synthesized and its folding and aggregation behavior has been elucidated in dependence on the solvent polarity. Extended cofacially π-stacked H-aggregates could be prepared in nonpolar solvents based on the preo
