Affordable solar energy moves closer


Nanosolar reports: [edited]

At Nanosolar, we have taken the highest-performance and most durable photovoltaic thin-film semiconductor, called CIGS (for "Copper Indium Gallium Diselenide"), and innovated on all seven critical areas necessary to reach a breakthrough cost reduction in solar cells, panels, and systems.

As opposed to using slow and expensive high-vacuum based thin-film deposition processes, we developed a proprietary ink to allow us to use much simpler and higher-yield printing for depositing the solar cell's semiconductor.

We use a highly conductive yet low-cost foil as a substrate, which allows us to avoid the need to separately deposit an expensive bottom electrode layer (as required for a non-conductive substrate such as glass).

Thanks to Sora for the link.
