本文描述了漂移扩散模型的应用，以说明量子点中间带太阳能电池（QD-IBSC）的操作和它的有效性限制。该模型的主要特点源于中间带太阳能电池（IBSC）是一种双少数载流子器件这一事实。的IB中的电流传输的作用进行了讨论，提供了有益的条件，在该电流接近零。电场也与中间带中的电流密度有关。的条件下，其中的电子和空穴漂移电流的贡献是小的总电流相比，进行了讨论。借助于数值例子来描述该单元的操作。
This paper describes the application of the drift-diffusion model in order to illustrate the operation of the quantum dot intermediate band solar cell (QD-IBSC) and its validity limits. The main particularities of the model arise from the fact that the intermediate band solar cell (IBSC) is a two-minority carrier device. The role of the current transport in the IB is discussed, providing the beneficial conditions in which this current approaches zero. The electric field is also related to the current density in the intermediate band. The conditions in which the contribution of the electron and hole drift currents is small when compared to the total current are discussed. The description of the operation of the cell is aided by means of a numerical example.
