Too strong of an accent, accompanied with the really poor transcript. Took too long to do the last assignment!
Silicon Thin Film Solar Cells
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://hua.dididi.sbs/learn/photovoltaic-solar-energy/) Physics of silicon solar cells (https://hua.dididi.sbs/learn/physics-silicon-solar-cells/) Silicon thin film solar cells

Both of the teachers are very conceptual,and ones can easily learn this course by giving some extra time.Thanks to the teaching staff and the team of coursera.

评论日期：Jun 7, 2020Very good course, i have learnt alot about thin solar cells such as c-Si, amorphous Si, nano-Si, combining them with other types of solar cell such as germanium-based solar cells to make multi-junction solar cells to improve their efficiencies. Furthermore, i have learnt about transparent conductive layer as well as the advantages and drawbacks of the different types of solar cell materials.

评论日期：Sep 26, 2020Very good course to get insight into the solar cells working however, more quiz questions can be given for practice, I have completed other courses also from Ecole Polytechnique, they have the best explanation and course material, looking forward for more such courses. Thanks, Coursera for bringing these courses on the platform.

评论日期：Sep 1, 2024In-depth lectures and great demonstration but requires some knowledge in advance. The annexes and quizzes are helpful. The transcript sometimes do not match the intended content. For instance: TCO layer --> tissue layer.

评论日期：Apr 19, 2020I think it would be better if materials such as how chemical elements/compounds are analyzed and selected for modeling more advanced PV cells. and advises on how can us student get into PV research.
Thank you.
