Performance of the FWPVs.
(a). I–V characteristics of FWPVs differing in size and number of attached solar cells. (b). ITRI-certified I–V data for two representative FWPVs. The 5 × 5 (FWSM-5) and 3 × 3 (FWSM-3) modules exhibited maximum powers of 115.79 and 50.09 mW, respectively. (c). Performance of 3 × 3 modules prepared with and without MLs. Inset: Lens profile; the radius (R), depth (D) and interval (L) were 0.50, 0.76 and 0.10 mm, respectively. The focal length (f) was calculated to be 5.0 mm. (d). I–V curves of the 5 × 5 2-cell FWPV under various bending conditions.
