More than one hundred of  the world’s first solar cells with EQE (External quantum efficiency)  were created recently showing significantly greater efficiency than regular solar cells. These enhanced solar cells generate 40% more power for every photon which falls on the solar cell. This achievement was possible with the help of Multiple Excitation Generation (MEG). MEG works by splitting and using a greater portion of the energy in the higher energy photons. The test results showed MEG produced an EQU value of 114 % for 4 eV photons. “Since current solar cell technology is still too expensive to completely compete with non-renewable… read more
