FIG. 2.

Current density vs voltage characteristics of devices with (solid) and without (dashed) nanoimprinting. Inset: IPCE spectra of both cells.

Image of FIG. 3.
FIG. 3.

Variation of (a) open-circuit voltage , (b) short-circuit current density , (c) FF, and (d) device efficiency with imprinting pressure. The duration time of imprinting is . Samples imprinted by a plain Si wafer, textured Si [refer to Fig. 1(a)], and textured Si with fewer pyramids than (b) are shown as closed squares, closed triangles, and open triangles, respectively.

Table I.

Properties of P3HT:PCBM solar cells with and without nanoimprinting. Two different stamps were used in the imprinting of the cells. and are series resistance and shunt resistance, respectively, measured in the dark.
