Microscopic measurements of variations in local (photo)electronic properties in nanostructured solar cells

Original language description

Modern nanostructured designs of solar cells improve photovoltaic conversion by better light trapping and collection of photogenerated charges. Illustrative example may be cells composed of radial junctions on semiconductor nanowires with 100 nm size. They exhibit variations of shape, size and properties which influence local photovoltaic conversion. The cells operate as random arrays of microscopic photodiodes connected in parallel with overall performance limited by weak diodes. We demonstrate the useof atomic force microscopy (AFM) with conductive cantilever for study of local (photo)electronic properties of silicon nanostructures: p?i?n radial junctions of amorphous Si grown on Si nanowires. We have used the conductive AFM to study the local photoresponse of the microcrystalline grains in mixed phase thin films to changes of external illumination. We discuss possibilities of comparing the local photoresponse to local photovoltaic conversion efficiency.
