Tiivistelmä
We report on the development of light-trapping architectures applied to
thin-film solar cells. In particular, we focus on enhancing the
absorption at 1-eV spectral range for dilute nitride and quantum dot
materials and report on the influence of planar back reflectors on the
photovoltaic properties. Moreover, we discuss the properties of polymer
diffraction gratings with enhanced light-trapping capability pointing to
advantageous properties of pyramidal gratings. In order to understand
the suitability of these polymer grating architectures for space
applications, we have performed an electron irradiation study (1 MeV)
revealing the absence of reflectance changes up to doses of 1×10
