NOVELTY - The method for forming a photovoltaic module (402), comprises disposing a back-electrode layer on a rigid elongated substrate, performing a first patterning on the back-electrode layer using a laser scriber or a constant force mechanical scriber, disposing a semiconductor junction on the back-electrode layer, performing a second patterning on the semiconductor junction using a mechanical scriber, disposing a transparent conductor layer on the semiconductor junction, and performing a third patterning on the transparent conductor layer using a mechanical scriber.    USE - The method is useful for forming a non-planar photovoltaic module, which is useful to form solar cells.    ADVANTAGE - The method is capable of effectively forming the non-planar cylindrical photovoltaic module with increased strength and stability thus improving the functionality and efficiency of the solar cells.    DETAILED DESCRIPTION - The method for forming a photovoltaic module (402), comprises disposing a back-electrode layer on a rigid elongated substrate, performing a first patterning on the back-electrode layer using a laser scriber or a constant force mechanical scriber, disposing a semiconductor junction on the back-electrode layer, performing a second patterning on the semiconductor junction using a mechanical scriber, disposing a transparent conductor layer on the semiconductor junction, and performing a third patterning on the transparent conductor layer using a mechanical scriber. The elongated substrate is rotated during the patterning steps. The patterning steps collectively create grooves in the back-electrode layer, the semiconductor junction and the transparent conductor layer. The semiconductor junction comprises an absorber layer, a window layer, a type III-V material and a type II-VI material, where the absorber layer comprises a type I-III-VI material. The photovoltaic module is characterized by a cross-sectional bounding shape that is circular, ovoid, a shape characterized by smooth curved surfaces, a splice of smooth curved surfaces, or an arcuate edge.
