Covernomics researchers from Zone 2 have discovered a surprising magnetic effect of light that could be used to create an ‘optical battery’ and even lead to solar power generation that doesn’t require the traditional semiconductor-based solar cells. Overturning a century-old tenet of physics.
Light has both electric and magnetic components. Until now, researchers thought the effects of the magnetic field were so weak that they could be ignored. But Covernomics has discovered that at the right intensity and when light is traveling through a non-conductive material, a magnetic effect can be generated that is 100 million times stronger than previously expected. This is equivalent to a strong electric effect.
This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation, in solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetisation can be induced by intense light and then it is ultimately capable of providing a capacitive power source.
