Paintable Solar Cells May Someday Replace Silicon-Based Panels

Rapidly expanding solar cell technology currently relies on expensive photovoltaic materials such as silicon or cadmium telluride, which is why their production, installation and maintenance costs are still high. Troy Townsend, an assistant professor of chemistry at St. Mary's College in St. Mary's City, Maryland, says less efficient but much cheaper inorganic materials could be used to create paintable solar cells. To make up for the low efficiency, this less expensive...
