Sharp Demonstrates Ultra-Efficient Solar Cells


The best solar cells convert less than one-third of the energy in sunlight into electricity, although for decades researchers have calculated that exotic physics could allow them to convert far more. Now researchers at Sharp have built a prototype that demonstrates one of these ideas. If it can be commercialized, it would double the amount of power a solar cell can generate, offering a way to make solar power far more economical.

The researchers figured out a way around a bothersome phenomenon: when sunlight strikes a solar cell, it produces some very high-energy electrons, but within a few trillionths of a second, those electrons shed most of their energy as waste heat.

The Sharp team found a way to extract these electrons before they give up that energy, thereby increasing the voltage output of their prototype solar cell.
