  • Efficient solar cells from silicon wires

    US researchers have designed a new silicon-based solar cell which uses 100 times less silicon than conventional photovoltaic devices. The system relies on the geometry of the silicon being reconfigured from a flat wafer to arrays of tiny silicon rods aligned vertically on the cell. Currently silicon solar cells are fabricated on brittle wafers of silicon around 100-200 micrometres thick. While ...

  • Getting More Electricity out of Solar Cells

    Original story at MIT News When sunlight shines on today’s solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons — behavior that could significantly increase solar-cell efficiency. An ...

  • Scientists set new record for solar cells efficiency

    Researchers at the Germany-based Fraunhofer Institute for Solar Energy Systems (ISE) announced that they have succeeded in improving the efficiency of solar cells, which are designed to convert available light into electricity. The quantum electronic phenomenon called the photovoltaic (PV) effect makes this possible. The team said the effectiveness of III-V semiconductor multi-junction solar ...

  • Nanopillars promise cheap, efficient, flexible solar cells

    Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials. The new design grows optically active semiconductors in arrays of nanoscale pillars, each a single crystal, with dimensions measured in billionths of a meter. “To take ...

  • New generation of solar cells promises efficiency

    The laboratory for photovoltaics of the University of Luxembourg has produced its first thin film solar cells made from compound semiconductors, already reaching a 12 percent efficiency. Thin film solar cells are considered the next generation of solar cells and are expected to be considerably cheaper because they need much less material and energy in their production than today's photovoltaic ...

  • Methods to increase indium supplies for the manufacture of thin-film solar cells

    Shortages of indium, a key metal found in thin-film solar cells, could limit their large-scale deployment in the future. A new study has outlined four ways that indium supplies could be increased to meet future demand. For example, indium could be extracted more efficiently from zinc ores, or historic wastes containing indium could be processed to extract the element. CIGS solar cells are a thin ...

  • Efficiency record of 17.6% on flexible CIGS solar cell on plastic developed at EMPA

    Flexible thin film solar cells on polymer film with a new record efficiency of 17.6% have been developed by the scientists at the Swiss Federal Laboratories for Material Science and Technology (EMPA). The conversion efficiency record has been independently certified by the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg, Germany.  Scientists under the leadership of Dr. ...
