Doug Renner sent this interesting URL about a new class of
solar cells with efficiencies which are more than twice
those in currently available solar cells;

The new technology is called triple-junction
gallium-indium-phosphide on gallium arsenide on germanium
concentrator solar cell.
"We have taken the basic cell design concept and made it
cost-effective for terrestrial applications when it is
combined with a concentrator system.
By doubling the power generating efficiency of the cell, the
size of the solar ray collection system can be reduced in
half, thereby reducing the overall cost of the
infrastructure," said Lillington.
Because the multi-junction cells are more efficient, only
about one-half of the real estate is require to generate the
same power output compared to crystalline silicon or
thin-film flat-plate modules, according to Spectrolab.
