Integration of a 2-D Periodic Nanopattern Into Thin-Film Polycrystalline Silicon Solar Cells by Nanoimprint Lithography

Nanoimprint lithography for high-efficiency thin-film silicon solar cells.

We demonstrate high-efficiency thin-film silicon solar cells with transparent nanotextured front electrodes fabricated via ultraviolet nanoimprint lithography on glass substrates. By replicating the morphology of state-of-the-art nanotextured zinc oxide front electrodes known for their exceptional light trapping properties, conversion efficiencies of up to 12.0% are achieved for micromorph tand...

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

Thin-film crystalline silicon solar cells

A photoelectric conversion efficiency of over 10% has been achieved in thin-film polycrystalline silicon solar cells which consists of a 2 μm thick layer of polycrystalline silicon with a very small grain size (microcrystalline silicon) formed by low-temperature plasma CVD. This has shown that if the recombination velocity at grain boundaries can be made very small, then it is not necessarily i...
