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 […]

To reduce even more the costs, these solar cells are build with an inexpensive ink-based process.

James Zahler from Aonex Technologies, together with colleagues from Harry Atwater’s group at the California Institute of Technology and researchers at EMCORE PhotoVoltaics made the device by replacing the relatively thick semiconductor substrate […]
