Solar Power Comes of Age
Solar Power for the Masses
Solar power is poised to enter the mainstream energy market with novel
materials that boost energy conversion efficiency and bring down
manufacturing costs.
Multi-junction cells based on amorphous silicon have been the most
successful second-generation technology todate. ... One such product on
the market is a triple-junction flexible solar panel [5] made of three
separate amorphous silicon layers, each with a different bandgap, so as
to harvest light from the entire solar spectrum, and works even in
cloudy conditions. It has a conversion efficiency of 13 percent; and a
test panel averaged nearly 70 percent of its rated maximum output during
the daylight hours of a typically grey British winter (1998/9).
