NOVELTY - The photovoltaic module (402) comprises a rigid elongated substrate (102), and solar cells linearly arranged on the elongated substrate. The solar cells comprise a first solar cell and a second solar cell. Each solar cell in the solar cells comprises a back-electrode layer disposed on the elongated substrate, a semiconductor junction (410) disposed on the back electrode, and a transparent conductor layer (110) disposed on the junction. The transparent conductor layer of the first solar cell is present in serial electrical communication with the back-electrode layer of the second solar cell.    USE - Used as a photovoltaic module.    ADVANTAGE - The photovoltaic module has enhanced solar cell efficiency, improved optical and chemical properties, and can be easily manufactured with enhanced light absorption and without physical or other damage.    DETAILED DESCRIPTION - The photovoltaic module (402) comprises a rigid elongated substrate (102), and solar cells linearly arranged on the elongated substrate. The solar cells comprise a first solar cell and a second solar cell. Each solar cell in the solar cells comprises a back-electrode layer disposed on the elongated substrate, a semiconductor junction (410) disposed on the back electrode, and a transparent conductor layer (110) disposed on the junction. The transparent conductor layer of the first solar cell is present in serial electrical communication with the back-electrode layer of the second solar cell. The semiconductor junction and the transparent conductor layer of a solar cell in the solar cells are patterned by a constant force mechanical scriber. The semiconductor junction of a solar cell in the solar cells comprises an absorber layer and a window layer. The absorber layer comprises a type I-III-VI material. The semiconductor junction of a solar cell in the solar cells comprises a type III-V material, and a type II-VI material. The elongated substrate has a Young's modulus of greater than or equal to 50 GPa, and comprises a linear material that obeys Hooke's law. The photovoltaic module is characterized by a cross-sectional bounding shape that is circular and/or ovoid and is characterized by smooth curved surfaces, a splice of smooth curved surfaces, and/or an arcuate edge.
