FIG. 1.

(Color online) Reflection (empty symbols) and EQE (dashed line) spectra for a cell patterned with a grating period . The corresponding spectra for a planar cell are also given for comparison (reflection spectrum in full symbols and solid line for the EQE). A scheme of the cell layers stacking is given in the upper left corner of the figure. The organic layer stacking is composed of a PEDOT film spin coated onto the ITO before the thermal evaporation of a CuPc layer, a layer, and a 2,9-dimethyl-4,7-diphenyl-1,10-phenantroline (BCP). The optical experimental setup is given in the upper right corner: T: tungsten lamp; BS: beamsplitter; C: solar cell; L: lens; F: optical fiber; S: spectrometer.

FIG. 2.

EQE spectra for cells patterned with different periods (a: ; b: ; c: ; d: ). Additional bands can be clearly distinguished at (a), (b), (c), (d).

FIG. 3.

(Color online) Experimental variation of the coupled wavelengths (symbols) versus the period . The dashed line represents the case of below which the light cannot be guided.
