Nanosolar- printed solar film

Nanosolar has developed technology to create solar panels by printing films 1/100th the thickness of absorber in a silicon-wafer cell. With the drastic cut in unit price that will come from this they hope to have a solar panel on every building.

There are issues with the lifespan of these thin film photovoltaics, and worries about toxicity of the chemicals used. If they can be answered, then this could be a huge step toward a solar future.
