课程名称：硅太阳能电池的物理学 课程概述：本课程是第一门关于“光伏太阳能”的MOOC，主要介绍全球能源背景下的太阳能光伏技术，没有过多的细节描述。特别是，太阳能电池的操作描述仅限于理想情况。与此不同，第二门MOOC则允许对基于晶体半导体的太阳能电池特性进行深入理解。该课程全面介绍了光伏设备的物理学，尤其强调当前市场占有率超过90%的硅技术，同时也提及了III-V族半导体的光伏应用。从基础的角度来看，太阳能电池可以被视为一个暴露在阳光下的半导体器件（一个二极管）。课程开始介绍半导体物理，随后讲解二极管中的电子输运现象。接着详细描述了太阳能电池的工作原理，包括转化效率的限制。此外，还将介绍太阳光谱和太阳能电池的光学特性。最后，课程详细描述了从大块晶体生长到结合晶体和非晶材料的异质结的硅技术。 课程大纲： 1. 半导体物理介绍 - 内容：介绍晶体半导体的能带结构、光学吸收和掺杂。 2. 输运现象：p-n结 - 内容：半导体中的载流子注入和复合现象；平衡与非平衡p-n结；光伏效应。 3. 不对称器件 - 内容：金属-半导体接触和半导体表面；异质结。 4. 太阳能电池的工作原理 - 内容：太阳光谱；太阳能电池的基础知识；转化效率的限制；太阳能组件。 5. 晶体半导体太阳能电池 - 内容：描述从大块晶体生长到III-V化合物太阳能电池的晶体硅光伏技术。 6. 硅异质结 - 内容：课程中进一步探讨异质结的应用及其在光伏技术中的重要性。 通过本课程，学员可以深入理解硅太阳能电池的物理原理与应用，为未来的研究与实践打下坚实的基础。

Name:SILICON HETEROJUNCTIONS
Description:
The first MOOC “Photovoltaic solar energy” is a general presentation of the solar photovoltaics technologies in the global energetic context, without extensive details. In particular the description of the solar cell operation is restricted to the ideal case In contrast this second MOOC allows a deep understanding of the properties of solar cells based on crystalline semiconductors. It consists in a general presentation of the physics of the photovoltaics devices with a particular emphasize on the silicon technology that currently represents more than 90% share of the market. Photovoltaic applications of III-V semiconductors are also mentioned. Indeed from a fundamental point of view, a solar cell can be considered as a semiconductor device (a diode) exposed to the sunlight. An introduction to the semiconductor physics is given, followed by the electron transport phenomena in a diode device. A detailed description of the solar cell operation is then provided, including the conversion efficiency limitations. A description of the solar spectrum and the optical properties of the cells are also presented. Finally the crystalline silicon technology is described from the bulk crystalline growth up to the preparation of heterojunctions combining crystalline and amorphous materials.
