TL;DR: A direct comparison with a cell deposited on the random pyramidal morphology of state-of-the-art zinc oxide electrodes, replicated onto glass using nanoimprint lithography, demonstrates unambiguously that periodic structures rival random textures.

TL;DR: In this article, a low-cost technique for implementing arbitrarily designed surface morphologies directly into functional zinc oxide films was demonstrated, achieving conversion efficiencies of 10.1% when applied the films as transparent front electrodes in amorphous silicon solar cells.

TL;DR: In this article, nanostructured silicon phases embedded in a silicon oxide matrix were implemented in thin film silicon solar cells and their combination with optimized deposition processes for the silicon intrinsic layers was shown to allow for an increased resilience of the cell design to the substrate texture, with high electrical properties conserved on rough substrates.

TL;DR: In this article, the use of intrinsic silicon oxide as a buffer layer at the p-i interface of thin-film silicon solar cells is shown to provide significant advantages, including an improvement in carrier collection in the blue region of the spectrum.

TL;DR: In this article, the authors identify three key requirements for the transparent conductive oxide electrodes: strong light scattering into large angles is needed on the entire useful wavelength range, sufficiently smooth substrate features are needed to guarantee a high quality of the silicon active material, ensuring good and stable electrical properties (typically Voc around 1.4
