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....
