The most common objection to solar energy is how costly it is. The construction of silicon panels of the proper design is quite the endeavor. Nanosolar took a different route. Its solar panels are composed of conductive substances such as copper alloys that are used as electrodes, a thin layer of which is printed (both time and cost-efficiently) over a metal foil. This is a great contrast to other solar panels, which are typically composed of thick layers of silicon over glass or stainless steel. Silicon is a poor conductor, and Nanosolar's method is much more efficient.
