Achieving higher photoabsorption than group III-V semiconductors in silicon using photon-trapping surface structures

Wayesh Qarony, Ahmed S. Mayet, Ekaterina Ponizovskaya Devine +8

The photosensitivity of silicon is inherently very low in the visible electromagnetic spectrum, and it drops rapidly beyond 800 nm in near-infrared wavelengths. Herein, we have exp…
