High aspect‐ratio three‐dimensional (3D) a‐Si:H solar cells have been fabricated to enhance a light absorption path while maintaining a short carrier collection length. Substantial efficiency enhancement in 3D solar cells was achieved due to the boost in J SC with no degradation of FF which is comparable to FF obtained from 2D solar cells.
