课程名称：硅薄膜太阳能电池 课程概述：本课程对基于硅薄膜的太阳能电池进行了总体介绍。这是法国高等科技学院（Ecole polytechnique）在Coursera上提供的光伏系列的第三门MOOC课程。光伏领域的一般知识在“光伏太阳能”课程中进行了讨论，而晶体硅太阳能电池的详细描述则可在“硅太阳能电池物理”课程中找到。 课程内容首先简要介绍了太阳能电池的工作原理，接着描述了薄膜半导体的特性。无序与晶体半导体在能带结构和掺杂机制方面存在显著差异。硅薄膜的厚度通常小于1微米，采用氢气掺杂的硅烷等离子体进行沉积。课程讨论了生长机制，尤其是能够制备部分晶化的薄膜，这类薄膜在非晶材料中嵌入了纳米晶体。 课程还回顾了半导体特性对太阳能电池性能的影响。非晶硅和纳米晶硅的光学特性互补，使得等离子体工艺特别适合于制备多结结构，其转换效率约为13-15%。此外，等离子体工艺还可以在玻璃或柔性衬底上大面积制备太阳能电池。 最后，课程展示了晶体硅和非晶硅材料可结合成异质结太阳能电池，具有约25%的高转换效率。 **本课程为三部分系列课程之一：** 1. 光伏太阳能（https://www.coursera.org/learn/photovoltaic-solar-energy/） 2. 硅太阳能电池物理（https://www.coursera.org/learn/physics-silicon-solar-cells/） 3. 硅薄膜太阳能电池 课程大纲： - 太阳能电池的工作原理：描述能量来源、太阳光谱，随后讲解基于半导体材料的太阳能电池的一般工作原理。 - 薄膜半导体：描述无序半导体的特性，接着介绍最常用的材料：氢化非晶硅。 - 硅薄膜太阳能电池：对硅薄膜太阳能电池和多结结构进行概述，随后介绍结合晶体硅和非晶硅的异质结。

Name:Silicon Thin Film Solar Cells
Description:A general review of silicon thin film solar cells and multijunctions followed by heterojunctions combining crystalline and amorphous silicon
This course consists of a general presentation of solar cells based on silicon thin films. It is the third MOOC of the photovoltaic series of Ecole polytechnique on Coursera. The general aspects of the photovoltaic field are treated in "Photovoltaic Solar Energy". And the detailed description of the crystalline silicon solar cells can be found in "Physics of Silicon Solar Cells". After a brief presentation of solar cells operation, thin film semiconductors are described here. The general properties of disordered and crystalline semiconductors are found very different, in particular in terms of band structure and doping mechanisms. Silicon thin films, generally less than 1 µm thick, are deposited from silane plasma leading to hydrogen incorporation. The growth mechanisms are discussed, in particular the capability to prepare partially crystallized thin films which appear as a mixture of nanocrystallites embedded in an amorphous tissue. The consequences of the semiconductor properties on solar cells behavior are reviewed. The optical properties of amorphous and nanocrystalline silicon are complementary. Thus the plasma process is particularly well adapted to the preparation of multijunctions, with conversion efficiencies around 13-15 %. Furthermore plasma processes allow to prepare solar cells in large area on glass or flexible substrates. Finally, it is shown that crystalline and amorphous silicon materials can be combine into heterojunctions solar cells with high efficiency conversion (about 25 %). **This course is part of a series of 3** Photovoltaic solar energy (https://www.coursera.org/learn/photovoltaic-solar-energy/) Physics of silicon solar cells (https://www.coursera.org/learn/physics-silicon-solar-cells/) Silicon thin film solar cells
