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.

Deben de estar bromeando¡ el primer examen de la sección LCA es realmente difícil debido a que varias de las preguntas en él, no fueron enseñadas o vistas. Por ejemplo, hay una pregunta que dice, "...how many m2 of solar energy is needed.... ?" e incluso se introducen conceptos que no fueron visto con anterioridad, como : "performance ratio" y "active area". Deberían de replantear las preguntas hechas allí o dar una lección sobre esos temas de otra manera, se ve muy difícil el terminar el curso así (casi imposible).

I started the course with high hopes, and i was beginning to enjoy the subject matter. But it became very tough for me to continue because the sound in the videos was not very clear. It became very difficult understanding what the instructors said, either because the placement of the mic was not very good or the instructors were not speaking very clearly

The discussion forum was unavailable. Also the amount of advanced chemistry required for this course is something I have not done either in high school or university level. That is why it was harder to follow Weeks 2 and 3 which covered materials of polymers

Poor interest if you want to know how to actually use OPV. The rythm is quite slow as well, it gets boring. All the information can be found much faster at

Not enough information is provided to pass some of the quizzes without extensive additional research into organic chemistry or other topics. There is no help forum or feedback from instructors

VERY LOW VIDEO QUALITY

The lessons are not very clear and have almost no examples. To make matters worse, the discussion forums were closed so you could not ask anything to clarify things, so it was very difficult to learn things here.

Quality of the video and sound are bad; a few minutes after starting a lesson, sound goes off or picture holds and moves no more... This made me stop the course.

Where is the material? There is nothing under any of the weeks lectures.

No forum + No email + No support whatsoever = Very frustrating

Extremely light on information, no discussion forums.
