Effect of oligothiophene spacer length on photogenerated charge transfer from perylene diimide to boron-doped diamond electrodes
Original language description
Organic-based photovoltaic devices emerged as a complementary technology to silicon solar cells with specific advantages in terms of cost, ease of deployment, etc. In this work, thin-film B:NCD electrodes are employed for their useful optical, electronic, and chemical properties. A set of oligothiophene perylene diimide donor-acceptor chromophores is designed and synthesized in order to investigate the influence of the oligothiophene spacer length when the molecule is attached to a B:NCD. XPS shows that the surface coverage decreases with increasing oligothiophene length. The maximum photovoltage is obtained for an intermediate oligothiophene length, providing an optimum between decreasing transport efficiency and increasing efficiency of charge separation and reduced recombination with increasing oligothiophene length. Holes transferred from nT-PDI to diamond persist there even after the illumination is switched off. Such features may be beneficial for application in solar cells.n
