solar energy and world peace solar energy news

conventional solar cells contain silicon, which captures sunlight and converts its energy to electricity. the panels are dark, because silicon absorbs light across a wide spectrum of wavelengths, allowing very little to pass through. this makes them efficient generators, but opaque materials, even though the thin silicon layer is coated on glass.
