abstract = {A solar cell is used to directly convert the sunlight into
electrical energy. The keyindicator for the performance of a
solar cell, hence for its competitiveness comparedwith other
forms of renewable energies is the conversion efficiency.
The conversionefficiency of a solar cell strongly depends on
its local optoelectronic properties, suchas local light
coupling efficiency or local material inhomogeneity, on the
microscopicor even nanoscopic length scales. Therefore, an
accurate understanding and assessmentof the specific effects
of these factors on the photogenerated current wouldprovide
valuable information for the improvement of the solar cell
performance. Thiswork presents local photocurrent
measurements of various thin-film silicon solar cellswith
subwavelength spatial resolution by using an aperture-type
scanning near-fieldoptical microscope (a-SNOM) as the
illumination source. The measurement methodallows for direct
access to the local optoelectronic properties. With the
support offinite-difference time-domain (FDTD) simulations,
their individual contributions tothe photocurrent generation
are analyzed....},
