A new discovery coming the Northwestern University could make solar cells embeddable in clothes and various fabrics. It involves changing tin, an important element of solar cells, with carbon nanotubes, considered more flexible and efficient. For a solar cell to be transparent and still function, it has to have several layers, of which a transparent […]

Yet another efficiency record has been established for mass-producible solar cells: 23.4%. The Fraunhofer Institute for Solar Energy Systems (ISE) from Germany succeeded to manufacture a single-crystal silicon solar cell of a thin p-type semiconductor layer residing on an n-type semiconductor substrate. The solar cell's area is 2x2cm.
