Figure 3: Physical morphology and performance characteristics of Blu-ray-patterned solar cells.
From: Repurposing Blu-ray movie discs as quasi-random nanoimprinting templates for photon management
(a) AFM images of the active layer without stamping and after stamping with a Blu-ray-patterned mould. The horizontal line profiles illustrate the depth contrast of the Blu-ray-patterned active layer. (b) Optical images of a half-patterned solar cell showing iridescent scattering due to the periodic nature of the Blu-ray pattern. (c) Reflected absorption (1−R) measurements from a Blu-ray-patterned solar cell. (d) Measured EQEs show a broadband enhancement and agree well with the calculated absorption spectrum in (c).
