Quantum Techniques to Enhance Solar Cell Efficiency

To achieve efficiencies higher than those for conventional solar cells, we need to take one extra step. The singlet fission material only absorbs the very energetic part of the spectrum, so that all the low-energy photons remain unused. Efforts in this field have therefore focused on combining the singlet… read more →
