提出了一个中间带太阳电池的模型，以评估载流子传输和复合(CTR)对这些器件效率的影响。该模型包括光学吸收、载流子寿命和载流子输运等物理参数对中间带电子态密度的依赖关系。模拟结果表明，当净载流子复合寿命较小时(纳秒范围内)或器件长度相对于载流子漂移长度较长时，转换效率降低。中间波段太阳能电池模型提供了一种基于CTR的可实验测量的输入参数来确定实际转换效率的方法。CTR的引入提供了基于载流子寿命和迁移率的中间带的最佳态密度和能量位置的依赖关系。以TeO(EG=2.3 eV，Ei=1.8 eV)材料为例，对中间带太阳电池模式进行了数值模拟.
A model for intermediate band solar cells is presented to assess the effect of carrier transport and recombination (CTR) on the efficiency of these devices. The model includes dependencies of physical parameters including optical absorption, carrier lifetime, and carrier transport on the density of intermediate band electronic states. Simulation results using this model indicate that conversion efficiency degrades when the net carrier recombination lifetime is small (range of nanoseconds) or when the device length is long relative to carrier drift length. The intermediate band solar cell model provides a method of determining realistic conversion efficiencies based on experimentally measurable input parameters for CTR. The incorporation of CTR provides insight on the dependence of optimal density of states and energetic position of the intermediate band based on carrier lifetime and mobility. The material ZnTeO (EG=2.3 eV, EI=1.8 eV) is used as a numerical example for the intermediate band solar cell mode...
