From: Inverted Silicon Nanopencil Array Solar Cells with Enhanced Contact Structures
Schematic illustration and 45° angle-view SEM images of different top electrode contact design with (a) metal directly deposited on top of the structure, (b) mesa bar metal strips and (c) low-platform metal strips before the metal stack deposition. It is noted that nanopencil arrays are employed here due to their observed superior light absorption characteristics for the improved PCE of fabricated solar devices. Schematics are not drawn in scale.
