Abstract

The absorption coefficient in organic polymers is known to be high ~107 m-1, thus requiring only a 100-300 nm thick film of polymer for complete absorption of visible light. However, the poor electron and hole lifetimes in organic polymers makes this short transit distances too long for the survival of the free charges and thus conventional electrodes are a handicap to enhancing the trend of increased efficiency of organic photovoltaic cells. The strategy we use to overcome this is to employ interdigitated electrodes (IDE) with nanometer spacing. The nanometer spacing (inter-electrode spacing) is such that the charges are collected before they recombine, i.e., the inter-electrode spacing should be shorter than the free carrier diffusion length.
