Solar Cells from Dyes Used in Jeans

Researchers at Cornell University (Ithaca, NY) say they have discovered a process for making solar cells with dyes used in the manufacture of blue jeans. The discovery is reported in a recent edition of the journal Nature Chemistry. Organic materials have long been recognized as having potential to create thin, flexible and low-cost photovoltaic devices, but it has proved difficult to organize their component molecules reliably into ordered structures likely to maximize device performance.   The new method is based on the use of a simple acid catalyst and...
