Abstract
A solar cell includes a p-type semiconductor substrate including a plurality of thin absorption regions and a plurality of thick absorption regions. The plurality of thin absorption regions and the plurality of thick absorption regions are coplanar on a bottom side thereof. An n-type semiconductor layer is disposed over a top side of the p-type semiconductor substrate. The n-type semiconductor layer has a substantially uniform thickness. Metallurgy is disposed on top of the n-type semiconductor layer. The plurality of thin absorption regions are sufficiently thin to render the semiconductor substrate flexible.
