Efficiency enhancement of organic solar cells by fabricating periodic surface textures using direct laser interference patterning

Adv Mater. 2012 Feb 14;24(7):906-10. doi: 10.1002/adma.201104331.

Abstract

Direct laser interference patterning (DLIP) is used to fabricate large area, two-dimensional periodic surface patterns on polyethylene terephthalate (PET) substrates to enhance the performance of ZnPc:C60 solar cells by light concentration in the absorber layer. Comparing the power conversion efficiencies to the reference cell on flat PET, a relative increase of 21% is observed for the hexagonal pattern with 0.7 μm period, depicted in the figure.
