[IEEE 2019 IEEE 13th International Conference on ASIC (ASICON) - Chongqing, China (2019.10.29-2019.11.1)] 2019 IEEE 13th International Conference on ASIC (ASICON) - Design of the admittance detecting circuit for silicon waveguides using the capacitor-integration method

摘要： The in?uences of the intermediate band (IB) ?lling, the absorption coef?cient constants, and the IB position on the ef?ciency of a quantum dot intermediate band solar cell (QD-IBSC) are investigated considering the spatial variation of subbandgap generation rates. A new de?nition of optimal intermediate band ?lling is proposed. A mathematical model is developed to optimize the intermediate band solar cell (IBSC) structure under idealized conditions, which calculates the optimal ratio of the subbandgap absorption coef?cient constants and the optimal position of IB.
