Comparison of reflectance spectrum between PU with different morphologies and blank groups. (a) shows the PU with PPY and IPY, (b) shows the ILC1500 and ILC900, (c) shows the PME1500 and PME900, (d) shows the PME400 and IME400, (e) shows the comparison between ILC1500 and commercial solar cells, and (f) shows the comparison between packing the ILC1500 and blank group by AR-glass.
