TL;DR: This study validates nanoimprinting as a versatile tool to investigate nanophotonic effects of a large variety of nanostructures directly on device performance by replicating the morphology of state-of-the-art nanotextured zinc oxide front electrodes known for their exceptional light trapping properties.

TL;DR: In this paper, the p-nc-SiOx with its particular nanostructure increases the efficiency of thin-film solar cells by reducing reflection and parasitic absorption losses depending on the roughness of the front electrode.

TL;DR: The optical and electrical properties of these mixed-phase nanomaterials can be tuned independently, allowing for advanced light management in high efficiency thin-film silicon solar cells and for band-gap tuning via quantum confinement in third-generation photovoltaics.

TL;DR: In this paper, the use of a silicon oxide interlayer between the active area and the back contact of the cell permits in such cases to improve the electrical properties of the cells, and relative increases of up to 7.5% of fill factor and of 6.8% of conversion efficiency are shown for amorphous silicon cells, together with improved yield and low-illumination performance.

TL;DR: In this article, the imprinting of random square based pyramidal textures with micrometric scale at the air/glass interface of thin film silicon solar cells is presented as an efficient alternative to anti-reflective coatings to minimize reflection losses at the cell entrance.
