Nanoimprint lithography for light trapping applications in solar cells
… arrays fabricated on the rear of the cells using nanoimprint lithography. A short-circuit current enhancement of 19% is measured experimentally, and excellent agreement with numerical simulations is obtained. We show numerically that by replacing the Ag capping present on the cells with a detached …

The effects of feature geometry on simulating nanoimprint lithography
Nanoimprint lithography (NIL) is a method for fabricating nano-scale patterns by pressing stamps into viscous materials. A key barrier to industry adoption of NIL is the inability to predict whether a stamp will imprint successfully and how long the process should be run for. In this thesis, we …
