The high efficiency of quantum dot solar cells is determined by the so-called multiple exciton generation (MEG) effect in quantum dots when a single photon is absorbed. The present work proposes a statistical approach to the process of simultaneous generation of many excitons in quantum dots when a high-energy photon is absorbed. This approach is based on the statistical Fermi approach to simultaneous generation of elementary particles (nucleons and π-mesons) in the nucleon-nucleon collision. Analysis of the results shows that the exciton quantum yields calculated using the statistical approach agree rather well with the experimental data.
