High scattering cross section of plasmonic nanoparticles in intermediate band solar cells (IBSCs) based on quantum dots (QDs) can obviate the low photon absorption QD layers. In this report, we present a modeling procedure to extract optical and electrical characteristics GaAs-based cell (PIBSC). It is shown that metal (MNPs) are responsible for incident photons absorber layer lead photocurrent enhancement, provided an optimum size density calculated. Proper design layers control energy location, as well loss-scattering trade-off MNPs, result efficiency increase ∼4.2% PIBSC compared similar IBSC, ∼5.9% reference GaAs PIN cell. A comprehensive discussion effect region width current-voltage designed presented.
