Abstract
The performance of hot carrier solar cells has been analyzed using a model incorporating the relaxation times of the relevant electronic processes. The variations in the maximum efficiency as well as the carrier statistics are demonstrated according to different carrier-carrier scattering rates. The significant dependance of cell performances on Coulomb scattering properties is quantitatively demonstrated and explained by carrier depletion, asymmetric electron and hole statistics, and unmatched transmission properties for carrier extraction. The inter-relation between the electronic properties of the absorber material and the contact properties implies that an integrated design with both parts is required.
