LiF/Al ZnO P3HT:PCBM

Inspired on the butterfly wing structure, a new cell design that responds the electronic and optical characteristic lengths of the organic materials

PEDOT:PSS ITO Glass

Patterned over larger surface area, the optical absorption is boosted and its electronic performance improved

Planar

Photonic

Optical redistributions at normal incidence for (a) planar and (b) PC cell for OPV-PT device. (c) Current - Voltage (J-V) properties for PC and planar cells follow absorption enhancement as predicted by the optical model.
