中文摘要： 高精度仿真和性能预测对太阳能电池设计和优化有重要作用。随着光伏技术的发展，传统低维电学计算或纯光学近似处理已难以满足日益多样的太阳能器件设计要求。本课题旨在构建基于频域和三维空间的光电一体仿真模型，通过严格分析太阳能电池在光学电学域的响应，准确得到系统全面的光学电学性能指标。本研究将在半导体材料光伏机制、模型稳定性和拓展性等方面突破现有模型局限，建立更为完善和普适性更强的三维光电设计系统。除单结太阳能电池外，还将模型拓展到多结以及多种微纳结构光伏系统。研究内容包括全矢量有限差分电磁建模、严格的三维空间电动力学建模以及单结/多结太阳能电池优化设计。着重针对典型单结和多结太阳能电池模拟全空间和频域中载流子的产生、输运、复合和收集等电动力学过程，以及光学吸收、光生电流、暗电流以及光电转换等光学电学现象。仿真结果将与文献实验进行对比，以验证和进一步优化模型。

英文摘要： Accurate simulation and performance prediction play an important role in the design and optimization of solar cells. With the progress of photovoltaic technologies, the conventional low-dimensional electronic calculation and purely optical approximation cannot satisfy the requirement for the design of the latest solar devices. This project aims to establish a simulation model integrated with both optical and electronic calculations in frequency domain, where the optical and electronic responses can be analyzed rigorously in order to obtain the accurate and complete performance parameters in both domains. This study will break the limits of previous model, by paying more attention to the photovoltaic mechanisms of the photovoltaic materials, the calcualtion stability, the model extendability, etc., for a more complete and extendable three-dimensional optical and electronic simulation system. Besides the single-junction solar cells, models for multi-junction and micro/nano-structured photovoltaic systems will be developed as well. The research topics include full-vector electomagnetic modelling based on finite-element method, rigorous three-dimensional electrodynamic modelling, and design of single- and multi-junction solar cells. We will especially concentrate on simulating the carrier processes including generat
