When a material has reached the limit of its strength, it usually has the option of either deformation or fracture. A naturally malleable metal can be made stronger by impeding the mechanisms of plastic deformation (reducing grain size, precipitation hardening, work hardening, etc.), but if this is taken to an extreme… the philadelphia story free

"WebA flexible solar module has an integral and internal thin metal foil, which is an integral layer of the solar cell stack. The thin metal foil collects and transports photovoltaic (PV) generated electric power from a plurality of regions of the solar module.
