Methods for manufacturing three-dimensional thin-film solar cells 100 , using a template. The template comprises a template substrate comprising a plurality of posts and a plurality of trenches between said plurality of posts. The three-dimensional thin-film solar cell substrate is formed by forming a sacrificial layer on the template, subsequently depositing a semiconductor layer, selectively etching the sacrificial layer, and releasing the semiconductor layer from the template. The resulting three-dimensional thin-film solar cell substrate may comprise a plurality of single-aperture unit cells or dual-aperture unit cells. Select portions of the three-dimensional thin-film solar cell substrate are then doped with a first dopant, while other select portions are doped with a second dopant. Next, emitter 525 and base metallization regions 532 are formed.
