Teachers explained amazingly and it was a very interesting course and may be beginning of my research career. thank you so much coursera atleast now i have a direction.\n\nLonging to learn a lot more.
It shows you how OPV works (which is a breakthrough technology) in a simple way without leaving the technical aspects of it.\n\nIt's a serious course that requires full compromise to achieve it.

Would like to get more information about physics behind OPVs

Too much formula based. Needs to be little more interesting.

FOR THE SOLAR LOVING PEOPLE IN THIS WORLD !!! LOVIN IT !!
By Beatriz M M•
A good introduction to the Organic Solar Cells world.
By Ebrahim F•
Hope we can get PART II of this course.
Thank you DUT
By Zhen Y•
Exceptional tutorials for getting to know the area
Great introduction to a very promising technology!
By Ms. S D•
it is useful to know about solar cells in detail
By Shrivaas S•
Really liking it though am still in week one :)
By Sparsh K•
Final exam shouldn't re-use quiz questions
By Camilla S•
Final quix should contain new questions
By Brian C•
Very thorough and helpful. Thank you.
By Jonathan B•
Great overview of organic solar cells

muy buen curso

The course is a good introduction to Organic Photovoltaics. The instructors have done a good job to present a rather complicated topic in a manner that is accessible to a common audience.
However, there are a few areas of improvement that can be noted for future versions of this course:
First, All material is given equal priority in the course. I think what the instructor can do is to summarize the important "take aways" at the end of each video lesson. This helps the learner grasp the concept better
Second, The explanation can be a little clearer - especially the topic of polymerization. Someone without an organic chemistry background, can find it frustratingly hard.
Third, the tests are sometimes not in line with the previous video lessons and the reading material. The tests should be much much sharper.
Fourth, the reading material should be improved vastly in terms of English quality, structure and presentation of key points. Sometimes, the learner can find it hard to understand some topics (ex: stability and materials) because it is inadequately explained. These topics should be explained better.
Overall, a great start - but can be better. Well done and Thank You!

The assignments should be flexible, i.e we should be given the score based on what we have answered and provided an opportunity to re-take them if we have to improve the score further instead of having a strict policy of getting all the answers correct in order to complete an assignment.
Further the lectures were as though the faculty is reading out from a board in front of them (with an exception of Frederik Krebs), and thus many concepts were only touched on the surface. For people with not much background in organic chemistry understanding PEDOT:PSS and other chemical components we tough.
A suggestion would be to increase the class duration and explaining the concepts in a more clear way.

I love the scale-up part of the course. It gives me a great insight of upscaling of solar cells. But in general, the course is lack of content in depth. I would prefer a more hard core course with detailed explanation of the working mechanism of solar cells.
By Aryan S•
Very easy to do, but at the cost of lack of depth. Even though I finished the course in about a week, I would love if it would have gone deeper as far as explanation goes. Very good introduction to OPVs.
By Liliana M C F•
In my opinion, the final exam was weak since it was compacting the quizzes throughout the course. The content could be 50% theory and 50% practice which i consider that it was more theoretical.
By Aditya S•
I think the quality of the course and quizzes must be improved. It is a very easy course. Please make the questions tougher and data of the course better.
By ullasa k•
I would suggest this course after the completion of " Introduction to solar cell " course to have have greater in depth understanding of this course.
