A great course for stepping in into solar power technology. The use of virtual instruments and the explanatory videos of Mr. Madsen and other scientists of the DTU are excellent resources to introduce and/or reinforce the concepts. The course is well designed and keeps you interested at most of the time.

Overall, I think this course is well organized, the content is clear and the use of didactic resources keeps it interesting. Also there are external links to more technical information. I enjoyed this course and would recommend it to anyone who is interested in this topic. I recommend to have some basic knowledge of electric behaviour of materials, circuits (Kirchoff, diodes), radiation and crystal structure for better understanding.

I would have liked for this course to go into more detail regarding the drawbacks of an intermitent energy production and the cost and energy required for the solution or minimization (eg. backup systems, accumulation). Also I think that it goes into too much detail regarding production of polymer solar cells, and the information of the emerging solar cells technologies (dye sensitized, quantum dot, perovskite) is poor and incomplete.

I am an Undergraduate student in Physics, of budding interest in Photovoltaics. I really enjoyed the course from day one till the end, being the instructor very kind and pleasing to the students introducing the fundamental concepts in a very novel manner, building it block-by-block. Also, the additional reading resources which were attached at the end of each module was really interesting and I can feel the excitement of going through the documentaries and the article references cited by the tutor. I was truly amazed by the potential of PV industry, which is portrayed in an exhaustive manner by the tutor. The course serves as a motivation to me to further enhance my knowledge on PVs, and I hope you will enjoy the course, if you're really,really motivated and pursuing a sustainable way of life/combating against Global warming via. Energy alternatives, specific to Photovoltaics. Free(!) Energy :)

This course introduced me to many different types of technologies out that are out there- especially emerging technologies that are not on the market yet. The beginning of the course is very heavy on science and math, which I think helped me understand how solar cells really work and proved that solar energy has a great potential. Be prepared to do many calculations. Later in the course, there is a lot of information to memorize. I think that the last lectures go into too much into detail on polymer solar cells and how they are made. These details might only be useful if you work in a lab or in manufacturing and would be better as optional material. Nevertheless, this course did leave me with a solid foundation to build on. I may or may not take the course on organic solar cells (also by DTU) after this.

Professor Madsen doesn't engage much, but that is generally due to the fact that he doesn't need to. His course material is thorough, though he assumes you know a bit more than you might in regards to what one might or might not consider to be entry-level college mathematics and sciences. Overall, the summary doesn't hit on a few technologies as thoroughly as I would have liked, but being that they are more emerging technologies, it's probably best to keep the material ambiguous as the technologies themselves advance. Glad I took the course, it's not perfect but it's absolutely satisfactory for what it is: An Introduction to Solar Cells

Firstly i would thank you instructor M.V Madsen for this course. It was highly appreciated because of its to the point lectures. I have gained an overview of the total solar technologies available currently. It was a very efficient course if anyone take it as introductory.

But there is one problem i have faced during this course. The sound volume of the lectures are too low. I have to concentrate higher to hear those lectures. If this problem can be solved, it is one of the best course i would recommend. I will take another course after this one, named organic solar cell technology provided by the same university.

The Introduction to solar cells course provides all resources needed to explore and dive into the fascinating field of solar energy conversion. The course addresses and embraces most important issues relevant to solar energy harvesting in a most interesting and comprehensive manner. Congratulations and thanks to DTU and course conductors, subject experts, researchers and everybody associated with the course.

There is some topics that are a bit of hard to understand, like the direct or undirect gap material. I'd say that the course was good for me, I really appreciate the introduction you've given me. I also found a bit of difficult the understanding of the different processes for generating printing on polymer solar cells, maybe it is difficult to understant just with the images.

Thanks!!

Course is really good introduction to renewable energy and understandings of solar cells. I would like to say thanks for all people who made it. For me, I would like also to include more review of current renewable energy market (for example which companies are doing what; mentions about Tesla's powerwall was interesting and I would like to hear more about solutions like that).
