CHEETAH Nano-MOOC:Designing dopant diffusions in silicon solar cells

December, 7th - 22nd 2017 - Online - CHEETAH webinar platform

Dr. Carlos del Cañizo  UPM-IES


CHEETAH e-learning platform has launched a series of nano-MOOCs Massive Online Open Courses  “Learning PV at Cheetah speed”  proposed and realized by Instituto de Energía Solar Universidad Politécnica de Madrid - IES-UPM under the leadership of prof. Carlos del Cañizo.

They are independent courses so any interested student, younger researcher and also, Engineers, R&D staff can register for just one of them, of for the three of them if they like.

Interested participants can follow at their own path, with an estimated student effort of around 20 hours hours of dedication from the student, including the presentations, readings and exercise.

They are very specific beyond “Fundamentals of PV”, focused on a relevant topic for researchers and PhD students, and accessible online, so that anyone can access based om his/her own needs and time availability.

The following courses were  launched, as a pilot experience, so if the esperience will be successful, the activity can also be transfered to upcoming intiative to share knowledge  in PV in very wide communities

  • Designing dopant diffusions in silicon solar cells

  • Circuit simulation of solar cells and modules

  • Advanced topics on solar cell



The first course of this series is offered by prof. Carlos del Cañizo and it is titled “Designing dopant diffusions in silicon solar cells”. The course will help students and younger scientists to go deeper into the topic with video-presentations, suggested readings and exercises.

The objectives of this course are the following :

  • To understand why we want to diffuse dopants in silicon solar cells, and what compromises appear regarding recombination, resistance and current collection
  • To review the theory of solid state diffusion to anticipate dopant profiles as a function of process temperature and duration, and learn the intricacies associated to the commonly used Phosphorus and Boron dopants
  • To design the process parameters for Phosphorus and Boron diffusions from liquid sources.
