Investigation of light harvesting complex LHCBM6 for dye-sensitized solar cells — •Fabian Schmid-Michels1, Nina Lämmermann2, Olaf Kruse2, and Andreas Hütten1 — 1Center for Spinelectronic Materials and Devices, Physics Department, Bielefeld University, Germany — 2Faculty of Biology, Algae Biotechnology & Bioenergy, Bielefeld University, Germany
Light harvesting complexes (LHC) or antenna complexes participate in photosynthesis by harvesting sunlight and transferring the excitation energy to the reaction centre. By channelling this energy elsewhere it is possible to use LHC either as a dye for dye-sensitized solar cells or as energy harvesters for artificial photosynthesis (AP). Solving this challenge could lead to a more efficient regenerative fuel production. To investigate LHCBM6, dye sensitized solar cells were prepared on ITO glass with the LCHs bound to TiO2 nanoparticles. Different binding types were evaluated by electrical measurements and microscopy (AFM, SEM).
