Bending and stability tests of the FWPVs.
(a). Photograph of a curved 5 × 5 2-cell module. The FWPV was readily bent because of its highly flexible waveguide. (b). Photograph of a twisted and bent 5 × 5 1-cell module. (c). PCEs of the 5 × 5 2-cell FWPV when bent at different radii. The efficiency increased upon decreasing the bending radius. (d). PCEs of the FWPV after various bending cycles. The FWPV maintained its efficiency almost completely after 1,000 bending cycles.
