Light trapping with titanium dioxide diffraction gratings fabricated by nanoimprinting

Wang, Er-Chien; Mokkapati, Sudha; White, Thomas; Soderstorm, Thomas; Varlamov, Sergey; Catchpole, Kylie


Dielectric scattering structures are a promising way of trapping light in solar cells. Titanium dioxide is a particularly attractive candidate material because of its high refractive index and ability to be deposited on a finished solar cell. Here, we present an experimental demonstration of photocurrent enhancement in thin film recrystallised silicon solar cells using TiO2 pillar arrays fabricated on the rear of the cells using nanoimprint lithography. A short circuit current enhancement of...[Show more]
