Optimization of Photolithographic Fabrication of Photonic Crystals and their Use in High Efficiency Solar Cells

Solar RRL, Volume 9, Issue 22, November 2025.
This study presents improved regular inverted pyramid structures, which should act as photonic crystals and thus are expected to highly increase light absorption. The prepared structures exhibit light trapping en par with random pyramid textured surfaces, but not as expected above.
