Abstract
In an effort to obtain efficient organic solar cells modeled on photosynthesis, photovoltaic cells from chlorophyll-a (Chl-a) have been fabricated. The cells are of Schottky barrier type in which Chl-a, a p-type semiconductor, is sandwiched as Langmuir-Blodgett films between Al and Ag electrodes. The power conversion efficiency of the cells is found to be approximately 0.05%, which is much smaller than the in vivo efficiency of approximately 16%. The processes of charge generation and transport in Chl-a were investigated by pulsed photoconductivity experiments. The data suggest that the efficient charge separation in a photosynthetic membrane is the result of the presence of certain structures, for example, Chl-protein complexes.
