Abstract
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 1×1015 e-/cm2.
