Solar Cell Circuit Model Explained
If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron – see the link above :). And a huge thank you to all my existing patrons – you make these videos possible.

Solar cells are ubiquitous in our modern world, and in this video I explain how we arrive at the circuit model for a solar cell, which is some current source in parallel with a diode.

This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren’s book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.

Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.

    Very intresting

    can a diode model be used for organic solar cell?

    Very interesting, the measurements in mm of a standard solar cell of how much would it be?

    You just need to incorporate drift, diffusion components to justify the diode current and photocurrent. Thanks for the attempt
