Figure 1. Green solar cell

Green solar cell (a) Schematic of green solar cell design (b) AM1.5G solar spectrum (dark blue) and solar spectrum after transmission of the nanoparticle array (green). Because green light is reflected from the nanoparticle array, the transmitted spectrum has a dip at 550-580 nm. Photographs under diffused sunlight (0.5 x 0.5 cm²) of (c) untreated solar cell and (d) green silicon heterojunction solar minimodule.
