Treehugger reports on a test of a “Gen-1” holographic solar module manufactured by Prism Solar Technology. By splitting the spectrum and focussing a specific wavelength on the photovoltaics efficiency is increased. Also, passive tracking of the sun can generate more power at different times of the day. The test found output was 25% more efficient than an equivalent area of plain photovoltaic, which one commenter calculated would reduce costs from $5/watt to $4.10/watt (initial cost, rather than per watt generated).
