Abstract
We propose the hybrid thermodynamic model using the intermediate band solar cells assisted with multiple exciton generation. We have calculated this thermodynamic model under blackbody radiation and standard AM1.5 spectrum and changed concentration to compare the conventional intermediate band solar cells. Because of multiple electron and hole pair at the conduction band edge, its maximum efficiencies and optimum bandgaps have been enhanced compared to conventional intermediate band solar cells. The maximum efficiencies of this solar cell are both 47.31 (Blackbody Radiation) and 49.85 (AM1.5G) percent for one sun and 65.07 (Blackbody Radiation) and 67.83 (AM1.5D) percent for maximum concentration. And its corresponding overall bandgap energies are also reduced because of multiple electron and hole pairs.
