Course Description

The goal of the course is to give students awareness of the largest alternative form of energy and how organic / polymer solar cells can harvest this energy. The course provides an insight into the theory behind organic solar cells and describes the three main research areas within the field i.e. materials, stability and processing.


  • Will I get a Statement of Accomplishment after completing this class?

    Yes. Students who successfully complete the class will receive a Statement of Accomplishment signed by the instructor.

  • What resources will I need for this class?

    For this course, all you need is an Internet connection and the time to read, write, and discuss.

  • What are organic solar cells?

    Organic solar cells also known as organic photovoltaic devices (OPV) are a type of solar cell that uses organic electronics. Subcategories of organic solar cells include polymer solar cells and small molecule solar cells.

  • What is roll to roll fabrication?

    In the field of electronic devices, roll to roll processing, also known as web processing, reel-to-reel processing or R2R, is the process of creating devices on a roll of flexible plastic or metal foil. This includes any coating and printing processes that are roll to roll compatible.


  • Week 1: Introduction to solar energy and the three generations of solar cells combined with an introduction to life cycle analysis for solar cells.
  • Week 2: Working principles of organic photovoltaics, how to measure and characterize organic solar cells and finally the application of organic solar cells.
  • Week 3: Materials for organic solar cells with focus on the active layer including common polymer materials, fullerenes, and low bandgap polymers.
  • Week 4: Stability and lifetime of organic and polymer solar cells.
  • Week 5: Production of organic solar cells with focus on roll to roll processes, coating, printing, and up-scaling.
  • Week 6: The future of organic solar cells and final exam.


The class will consist of lecture videos, which are between 8 and 12 minutes in length. These contain 1-2 integrated quiz questions per video. There will also be homework that is not part of the video lectures, and a final exam.

Suggested Reading

The reading material for the course will consist of a number of scientific articles, which will all be open access. In addition we will publish material on All the material will be made available during the course.

We also encourage students to order a free solar cell at This solar cell is a polymer solar cell made using roll to roll coating.
